Description
Zusatzpatent zum Hauptpatent Nr. 412319 Flüssiger Stabilisator für Polyvinylchlorid und Polyvinylchloridmischpolymere Gegenstand des Schweizer Patentes Nr.
412 319 ist ein flüssiger Stabilisator für Polyvinylchlorid und Poly- vinylchloridmischpolymere, der Barium-, Zink- und/ oder Cadmiumseifen epoxydierter geradkettiger Fett säuren und flüssige organische Lösungsmittel, die weichmachend und/oder stabilisierend wirken, enthält.
Diesen Lösungen können zur Erhöhung der synergisti- sehen Wirkung auch noch Seifen verzweigter, kurzket- tiger, aliphatischer Carbonsäuren oder Metall alkylphe- nolate zugesetzt werden.
Es hat sich gezeigt, dass sich die Barium-, Zink- und Cadmiumseifen geradkettiger epoxydierter Fettsäu ren durch andere Metallseifen ersetzen lassen.
Die vor liegende Erfindung betrifft dementsprechend einen flüssigen Stabilisator für Polyvinylchlorid und Polyvi- nylchloridmischpolymere, der dadurch gekennzeichnet ist, dass er Lithium-, Natrium-, Kalium-, Caleium-, Strontium-, Magnesium-, Beryllium-, Nickel-, Man gan-, Zinn-, Cer-,
Wismut oder Kobaltseifen epoxy- dierter geradkettiger Fettsäuren gelöst in organischen Lösungsmitteln, die weichmachend oder stabilisierend wirken, enthält.
Als Lösungsmittel dienen., ebenso wie bei den Sta bilisatoren der Hauptanmeldung, organische Lösungs mittel, die mit den zu stabilisierenden Polymeren ver träglich sind, als Weichmacher wirken oder zusätzlich stabilisierende Eigenschaften auf das Polymere aus üben bzw. den stabilisierenden Effekt der genannten Metallseifen erhöhen. Geeignete Lösungsmittel sind Alkylphenole, wie z.
B. 2-Isopropylphenol, 2-Methyl- 4-tert.-Propylphenol, 2,4-Dimethylphenol, 2,5-Dime- thylphenol, p-Nonylphenol. Als Lösungsmittel und zur Erhöhung der Stabilisierungseigenschaften eignen sich auch verschiedene hydroxylhaltige aliphatische Verbin dungen, wie z.
B. aliphatische gesättigte und ungesät tigte Polyalkohole oder Alkanolamine mit mindestens zwei Hydroxylgrappen, deren partielle Ester oder Äther mit mindestens einer freien Hydroxylgruppe, wie Glykol, Glycerin, Glycerinmonooleat, Glykoldiäthyl- äther, Propylenglykol, Hexylenglykol, Hexindiol,
Tri- üthanolamin. Sehr gut geeignet als organische Lösungs- mittel sind auch die sogenannten Mineralölextender, besonders diejenigen mit hohem Naphthen- und Paraf- fingehalt, sowie die an sich bekannten Phosphitverbin- dungen, wie z.
B. nichtflüchtige Triester der phosphori- gen Säure der allgemeinen Formel P(OR)3, in der R Alkyl- oder Arylreste sein können, beispielsweise Tri- phenylphosphit, Monooctyldiphenylphosphit, Trioctyl- phosphit, Monooctylpropylenglykolphosphit. Diese organischen Lösungsmittel können für sich allein oder,
soweit sie miteinander verträglich sind, auch in den verschiedensten Gemischen miteinander verwendet werden.
Die genannten Metallsalze epoxydierter geradketti- ger Fettsäuren sind in den vorerwähnten Lösungsmit teln meist gut löslich, so dass es gelingt, hochkonzen trierte Stabilisatorlösungen herzustellen und Seifen ver schiedener Metalle für bestimmte Anwendungszwecke miteinander zu kombinieren. So ist es möglich, schwe felunempfindliche flüssige Stabilisatorkombinationen auf Basis von Kalzium, Barium, Zink, Lithium,
Natrium und Kalium herzustellen. Nichttoxische Stabi lisatoren lassen sich mit einer Kombination von Kal zium, Magnesium und Zink erhalten.
Die Epoxyfettsäuren, deren Seifen zur Herstellung ider erfindungsgemässen Stabilisatoren dienen, können nach an sich bekannten Methoden durch Epoxyäierung der Äthylenbindung bzw. der Äthylenbindungen natür lich vorkommender ungesättigter Fettsäuren, wie z. B. Ölsäure, Palmitoleinsäure, Ricinoleinsäure oder Linol- säure, erhalten werden.
Die stabilisierende Wirkung der genannten Metall seifen epoxydierter geradkettiger Fettsäuren kann durch Zusatz von Metallseifen verzweigter, kurzketti- ger, aliphatischer Carbonsäuren noch synergistisch ver stärkt werden.
Als Metallkomponente dieser Seifen eig- nen sich gleichfalls die Alkali- und Erdalkalimetalle sowie Beryllium, Zink, Nickel, Mangan, Zinn, Cer, Wismut und Kobalt. Als Säurekomponente kommen einerseits u- oder ss-verzweigte aliphatische Carbonsäu- ren mit 5-7 Kohlenstoffatomen in gerader Kette, wie z.
B. a-Äthylhexansäure, a-Methylheptansäure, a-Me- thylvaleriansäure oder die entsprechenden f-verzweig- ten Säuren und anderseits stark verzweigte oder cycli- sche aliphatische Carbonsäuren mit 9-19, insbesondere 9-11 Kohlenstoffatomen, in Frage. Diese letztgenann ten synthetischen Säuren; nach ihrem Erfinder auch Koch-Säuren genannt, werden durch Anlagerung von Kohlenmonoxyd und Wasser an höhere Olefine erhal ten.
Sie sind beispielsweise in der deutschen Patent schrift 942 987 oder in Fette, Seifen, Anstrichmittel 59 (1957), S.493-498 beschrieben. Die Salze dieser Säuren sind in den infragekommenden Lösungsmittel- gemisehen bis zu etwa 60 11,10 löslich; sie zeigen in Kom bination mit den Seifen epoxydierter geradke-ttiger Fettsäuren nicht nur eine synergistisch verstärkte Wirksamkeit, sondern auch eine gegenseitige Löslich keitsbeeinflussung im Sinne einer Verminderung der Viskosität gegenüber der Viskosität bei gleicher Kon zentration der Einzelkomponenten.
Auch Kombinationen der Metallseifen epoxydierter geradkettiger Fettsäuren mit Metallalkylphenolaten oder Kombinationen von Metallseifen epoxydierter geradkettiger Fettsäuren und verzweigter, kurzkettiger, aliphatischer Carbonsäuren mit Metallalkylphenolen haben sich als brauchbar erwiesen. Diese Metallalkyl- phenolate leiten sich zweckmässig von den gleichen Alkylphenolen ab, die als Lösungsmittel für die Metall verbindungen Verwendung finden.
Die Herstellung der erfindungsgemässen Metallsei- fenlösungen kann nach der Beschreibung im Hauptpa tent erfolgen, wobei die endgültige Lösungstemperatur der Metallsalze den übrigen Lösungspartnern derart angepasst wird, dass eine möglichst geringe Verfärbung auftritt.

Additional patent to main patent No. 412319 Liquid stabilizer for polyvinyl chloride and polyvinyl chloride copolymers Subject of Swiss patent No.
412 319 is a liquid stabilizer for polyvinyl chloride and polyvinyl chloride copolymers, which contains barium, zinc and / or cadmium soaps of epoxidized straight-chain fatty acids and liquid organic solvents that have a plasticizing and / or stabilizing effect.
To increase the synergistic effect, soaps of branched, short-chain, aliphatic carboxylic acids or metal alkyl phenolates can also be added to these solutions.
It has been shown that the barium, zinc and cadmium soaps of straight-chain epoxidized fatty acids can be replaced by other metal soaps.
The present invention accordingly relates to a liquid stabilizer for polyvinyl chloride and polyvinyl chloride copolymers, which is characterized in that it contains lithium, sodium, potassium, potassium, strontium, magnesium, beryllium, nickel, manganese , Tin, cerium,
Contains bismuth or cobalt soaps of epoxidized straight-chain fatty acids dissolved in organic solvents that have a softening or stabilizing effect.
As a solvent, as in the case of the stabilizers of the main application, organic solvents that are compatible with the polymers to be stabilized act as plasticizers or additionally exert stabilizing properties on the polymer or increase the stabilizing effect of the metal soaps mentioned. Suitable solvents are alkylphenols, such as.
B. 2-isopropylphenol, 2-methyl-4-tert-propylphenol, 2,4-dimethylphenol, 2,5-dimethylphenol, p-nonylphenol. Various hydroxyl-containing aliphatic compounds are also suitable as solvents and to increase the stabilizing properties, such as.
B. aliphatic saturated and unsaturated polyalcohols or alkanolamines with at least two hydroxyl groups, their partial esters or ethers with at least one free hydroxyl group, such as glycol, glycerol, glycerol monooleate, glycol diethyl ether, propylene glycol, hexylene glycol, hexynediol,
Triethanolamine. The so-called mineral oil extenders, especially those with a high naphthene and paraffin content, as well as the phosphite compounds known per se, such as, for example, are also very suitable as organic solvents.
B. non-volatile triesters of phosphorous acid of the general formula P (OR) 3, in which R can be alkyl or aryl radicals, for example triphenyl phosphite, monooctyl diphenyl phosphite, trioctyl phosphite, monooctyl propylene glycol phosphite. These organic solvents can be used on their own or
as far as they are compatible with one another, they can also be used in a wide variety of mixtures with one another.
The mentioned metal salts of epoxidized straight-chain fatty acids are usually readily soluble in the aforementioned solvents, so that it is possible to produce highly concentrated stabilizer solutions and to combine soaps of different metals for specific purposes. It is possible to use liquid stabilizer combinations based on calcium, barium, zinc, lithium,
Manufacture sodium and potassium. Non-toxic stabilizers can be obtained with a combination of calcium, magnesium and zinc.
The epoxy fatty acids, the soaps of which are used to prepare ider stabilizers according to the invention, can, according to methods known per se, by epoxyäierung of the ethylene bond or the ethylene bonds naturally occurring unsaturated fatty acids such. B. oleic acid, palmitoleic acid, ricinoleic acid or linoleic acid can be obtained.
The stabilizing effect of the metal soaps mentioned, epoxidized straight-chain fatty acids can be synergistically strengthened by adding metal soaps of branched, short-chain, aliphatic carboxylic acids.
The alkali and alkaline earth metals as well as beryllium, zinc, nickel, manganese, tin, cerium, bismuth and cobalt are also suitable as metal components of these soaps. On the one hand, u-branched or ss-branched aliphatic carboxylic acids with 5-7 carbon atoms in a straight chain are used as acid components, e.g.
B. a-ethylhexanoic acid, a-methylheptanoic acid, a-methylvaleric acid or the corresponding f-branched acids and, on the other hand, highly branched or cyclic aliphatic carboxylic acids with 9-19, in particular 9-11 carbon atoms, are possible. These latter synthetic acids; Also called cooking acids after their inventor, are obtained by the addition of carbon monoxide and water to higher olefins.
They are described, for example, in German Patent 942 987 or in Fette, Seifen, Anstrichmittel 59 (1957), pp. 493-498. The salts of these acids are soluble in the solvent mixtures in question up to about 60 11.10; In combination with the soaps of epoxidized straight-chain fatty acids, they not only show a synergistically increased effectiveness, but also a mutual solubility influence in the sense of a reduction in viscosity compared to viscosity with the same concentration of the individual components.
Combinations of the metal soaps of epoxidized straight-chain fatty acids with metal alkyl phenolates or combinations of metal soaps of epoxidized straight-chain fatty acids and branched, short-chain, aliphatic carboxylic acids with metal alkyl phenols have also proven to be useful. These metal alkyl phenolates are advantageously derived from the same alkyl phenols that are used as solvents for the metal compounds.
The metal soap solutions according to the invention can be produced according to the description in the main patent, the final solution temperature of the metal salts being adapted to the other solution partners in such a way that the least possible discoloration occurs. In general, solution temperatures of 130 ° C. to 140 ° C. are not exceeded.
