Geeignete Acyloine sind beispielsweise das Benzoin oder dessen Derivate, wie p-Dimethylaminobenzoin, ferner Benzfuroin, Furoin, auch aliphatische Acyloine, die mindestens einen aliphatischen Rest mit wenigstens 6 bis io C-Atomen enthalten, und z.

Suitable acyloins are, for example, benzoin or its derivatives, such as p-dimethylaminobenzoin, also benzfuroin, furoin, also aliphatic acyloins which contain at least one aliphatic radical with at least 6 to 10 carbon atoms, and z.

Dieser Zusatz 1ewirkt eine weitere Weichmachung des Produktes, Aufhellung der Eigenfarbe der gepreßten Platten, besonders bei der Alterung, sowie eine deutliche Verbesserung der Spritzbarkeit.Example i In the rolled head of a copolymer made of 70% styrene and 30% butadiene becomes 10% plasticizer, dibutyl thiodibutyrate and additionally i% benzoin mixed in. This addition 1 works another softening of the product, lightening of the inherent color of the pressed panels, especially in the case of the Aging, as well as a significant improvement in sprayability.

Beispiel 2 In gleicher Weise erhöht ein geringer Zusatz von Benzoin zu einer Mischung aus Polyvinylchlorid und einem Weichmachungsmittel die Weichmacherwirkung des verwendeten Weichmachungsmittels unter gleichzeitiger Verbesserung der Transparenz und Alterungsbeständigkeit.Example 2 In the same way, a small addition of benzoin increases to a mixture of polyvinyl chloride and a plasticizing agent, the plasticizing effect of the plasticizer used with a simultaneous improvement in transparency and aging resistance.
