Description
La présente invention concerne des catalyseurs solides utilisables pour la polymérisation de composés oléfiniques tels que l'éthylène, le propylène, le styrène, le chlorure de vinyle, etc.
Il est connu d'utiliser pour la polymérisation de monomères oléfiniques des catalyseurs obtenus par action de composés
<EMI ID=1.1>
du système périodique sur des métaux, alliages, hydrures ou composés organo-métalliques des éléments des 1er à 3 groupes du système périodique.
Les catalyseurs généralement préconisés sont obtenus par action de tétrachlorure de titanes, de tétrachlorure de zirconium ou d'acétylacétonate de chrome sur un composé organométallique d'aluminium, de magnésium ou de zinc.
Il a maintenant été découvert que des catalyseurs très efficaces peuvent être obtenus en faisant agir les mêmes composés
<EMI ID=2.1>
des composes à action réductrice des métaux choisis dans les sousgroupes b des mènes groupes 4 à 6 du tableau des éléments.
Les composés des sous-groupes a. pouvant intervenir
dans la préparation du catalyseur sont, par exemple, les tétrachlorures de titane, de zirconium, de thorium et de vanadium, les pentachlorures de tantale et de molybdène, l'oxychlorure et l'acétylacétonate de chrome, etc.
<EMI ID=3.1>
groupes doués de propriétés réductrices sont, par exemple, des métaux, des alliages, des hydrures, comme l'hydrure d'étain, le tétrahydrure de germanium, des hydrures de silicium,etc; les composés organo-métalliques tels que le plomb tétraméthyle, le plomb et
<EMI ID=4.1>
méthyle, etc.
Pour l'obtention de polymères à poids moléculaire élevé, on utilise avantageusement un excès des composés des sous-groupes
<EMI ID=5.1>
Exemple I.
Dans un réacteur, on verse dans l'ordre, 100 cm<3> de ben-
<EMI ID=6.1>
tétrachlorure de titane.
On laisse agir pendant 8 heures, sous agitation, à 50[deg.]C. Lorsque la réaction est terminée, on ajoute 10 cet d'alcool méthy-
<EMI ID=7.1>
reflux., avec de l'acide chlorhydrique concentré pour dissoudre les produits inorganiques et décomposer le composé organo-métallique.
Après lavage à l'eau chaude, on verse la solution benzé-
<EMI ID=8.1>
do précipiter le polymère.
The present invention relates to solid catalysts which can be used for the polymerization of olefinic compounds such as ethylene, propylene, styrene, vinyl chloride, etc.
It is known to use for the polymerization of olefinic monomers catalysts obtained by the action of compounds
<EMI ID = 1.1>
of the periodic system on metals, alloys, hydrides or organo-metallic compounds of the elements of the 1st to 3 groups of the periodic system.
The catalysts generally recommended are obtained by the action of titanium tetrachloride, zirconium tetrachloride or chromium acetylacetonate on an organometallic compound of aluminum, magnesium or zinc.
It has now been discovered that very efficient catalysts can be obtained by making the same compounds act.
<EMI ID = 2.1>
compounds with a reducing action of the metals chosen from subgroups b of the same groups 4 to 6 of the table of elements.
Compounds of subgroups a. can intervene
in the preparation of the catalyst are, for example, titanium, zirconium, thorium and vanadium tetrachlorides, tantalum and molybdenum pentachlorides, chromium oxychloride and acetylacetonate, etc.
<EMI ID = 3.1>
Groups endowed with reducing properties are, for example, metals, alloys, hydrides, such as tin hydride, germanium tetrahydride, silicon hydrides, etc; organometallic compounds such as tetramethyl lead, lead and
<EMI ID = 4.1>
methyl, etc.
To obtain polymers with a high molecular weight, an excess of the compounds of the subgroups is advantageously used.
<EMI ID = 5.1>
Example I.
In a reactor, we pour in order, 100 cm <3> of ben-
<EMI ID = 6.1>
titanium tetrachloride.
It is left to act for 8 hours, with stirring, at 50 [deg.] C. When the reaction is complete, 10 cc of methyl alcohol is added.
<EMI ID = 7.1>
reflux., with concentrated hydrochloric acid to dissolve inorganic products and decompose the organometallic compound.
After washing with hot water, the benzene solution is poured in.
<EMI ID = 8.1>
do precipitate the polymer.
