Wie aus der belgischen Patentschrift 637 443 bekannt ist, werden organische Stoffe durch Mischungen
phenolischer Verbindungen und Thio-dipropionsäuredilaurylester stabilisiert. Es wurde nun überraschend
gefunden, daß Alkylmercaptomethylbernsteinsäurediester als Costabilisatoren für phenolische
Antioxydantien den Thio - dipropionsäuredilaurylestern bei der Stabilisierung von mono- und polymeren
aliphatischen Kohlenwasserstoffen überlegen sind.
Gegenstand der Erfindung ist deshalb die Verwendung von Diestern der Alkylmercaptomethylbernsteinsäure
der allgemeinen Formel I
II
R1-S-CH2-CH C-O-R2 (I)
CH2-C-O-R3
worin Ri eine Alkylgruppe mit 8 bis 18 und vorzugsweise 12 bis 18 Kohlenstoffatomen und R2 und R3
jeweils eine Alkylgruppe mit 12 bis 18 Kohlenstoffatomen bedeuten, im Gemisch mit bekannten pheno-
lischen Antioxydantien, zum Stabilisieren von monooder -polymeren aliphatischen Kohlenwasserstoffen.
Ri, Ra und R3 können identisch oder untereinander verschieden sein und im Rahmen der vorstehenden
Definition beispielsweise gerade oder verzweigte Alkylgruppen, wie Octyl-, Nonyl-, Decyl-, Undecyl-,
Dodecyl-, Tridecyl-, Tetradecyl-, Pentadecyl-, Hexadecyl-, Heptadecyl- oder Octadecylgruppen, bedeuten.
Erfindungsgemäß verwendbare Verbindungen der Formel I sind z. B. Dodecylthiomethylbernsteinsäüre-di-dodecylester,
Octadecylthiomethylbernsteinsäure-di-dodecylester, Dodecylthiomethylbernsteinsäure-di-octadecylester,
Octadecylthiomethylbernsteinsäure-di-octadecylester und Octylthiomethylbernsteinsäure-di-dodecylester.
Die erfindungsgemäß verwendeten Verbindungen besitzen die Eigenschaft, die Wirkung zahlreicher
anderer Stabilisatoren, die die Zersetzung mono- oder polymerer aliphatischer Kohlenwasserstoffe verlangsamen,
sehr stark zu erhöhen. In Verbindung mit bekannten phenolischen Stabilisatoren steht die
Stabilisier.ungswirkung in einem weit höheren Maß, als sich dies nach der Summe der Eigenschaften der
Einzelkomponenten erwarten ließe. ,

gegen die Zersetzung stabilisiert werden und sich daher für die alleinige wie auch für die zusätzliche Einverleibung
von Verbindungen der Formel I eignen, sind beispielsweise Poly-a-olefine, wie Polyäthylen,
Polypropylen, Polybutylen oder Polyisopren, einschließlich Copolymerisaten von Poly-a-olefinen und
Copolymerisate, wie hochschlagfestes Polystyrol, das Copolymerisate von Butadien und Styrol enthält.
Weitere erfindungsgemäß stabilisierbare Stoffe sind z. B. gesättigte und ungesättigte Kohlenwasserstoffe,
wie beispielsweise natürliche und synthetische Benzine, Düsenbrennstoffe, Dieselöle, Mineralöle, Heizöle
oder Paraffinwachse.
Typische bekannte phenolische Antioxydantien, deren stabilisierende Eigenschaften durch Zusatz der
erfindungsgemäßen Verbindungen der Formel I verbessert werden können, sind folgende:

Verbindungen verbessert werden können, zählen auch die Di-nieder?-;:y3phosphonate, die in der
USA.-Patentschrift 3 (ii)6 945 beschrieben sind. Be- 25 sonders wertvolle phenolische Phosphonate sind in
dieser Hinsicht jedoch die Di-iicberalkylphenolphosphonate, d. h. solche, die in jeder Alkylgruppe

Es empfiehlt sich oft, die vorstehend genannten phenolischen Stabilisatoren mit noch anderen Zusatzstoffen
zu verwenden, wie UV-Absorbern, z. B. 2-Hydroxy-4-methoxybenzophenon, 2-(2'-Hydroxy-5'-methylDhenyl)-benztriazol
oder wie Phosphitverbindungen, z. B. Trioctylphosphit, Dilaurylphosphit, Tris-(nonylphenyl)-phosphit. Solche Mischungen aus
drei oder vier Komponenten besitzen Eigenschaften, die der Summe der Eigenschaften der Einzelkomponenten
weit überlegen sind.
Je nach der Art der zu stabilisierenden Kohlenwasserstoffe können ihnen häufig auch noch andere
Stoffe zugesetzt werden, so z. B. Mittel zur Herabsetzung des Fließpunktes, Korrosionsschutzmittel,
Metallchelierungsmittel, Antischaummittel, Ruß, Beschleuniger, Weichmacher, Farbstabilisatoren, Wärmestabilisatoren,
Farbstoffe.
DieAlkylmercaptomethylbernsteinsäurediester werden vorzugsweise in einer Konzentration von 0,005
bis etwa 10 Gewichtsprozent des gesamten Stoffgemischs, zusammen mit den vorstehend genannten
phenolischen Antioxydantien, verwendet. Sie sind besonders geeignet, um synthetische organische polymere
Substanzen, wie Polypropylen, Polyäthylen und Polystyrol vor Zersetzung während des Gebrauchs
und während der Herstellung — im Falle von Polypropylen beispielsweise während des Walzens
oder bei Polyäthylen während des Blasformens— zu schützen. Die erfindungsgemäßen Verbindungen
der Formel I besitzen zu den verschiedensten Kohlenwasserstoffen und deren Polymeren ausgezeichnete
Verträglichkeit mit geringer oder ohne Geruchsbildung.
Die Verbindungen der Formel I erhält man durch Umsetzen von Itaconsäure-anhydrid mit einem geeigneten
Alkohol in Gegenwart von p-Toluolsulfonsäure und anschließender überführung des entstandenen
Itaconsäurediesters mit einem Alkylmercaptan in Gegenwart von Natriummethylat in den Diester
einer Alkylmercaptomethylbernsteinsäure. Man kann aber auch Mercaptomethylbernsteinsäure mit einem
Alkohol verestern. Nach einem weiteren Herstellungsverfahren wird die Alkylmercaptomethylbernsteinsäure
mit einem geeigneten Alkohol zum gewünschten Diester umgesetzt.
Die folgenden Beispiele dienen der näheren Erläuterung der Erfindung und schränken diese nicht ein.
Prozente beziehen sich darin auf das Gewicht, und Gewichtsteile verhalten sich zu Volumteilen wie
Gramm zu Kubikzentimetern. Temperaturen sind in Grad Celsius angegeben.
