摘要: Epoxidized and subsequently cross-linked esters of alcohols which are at least dihydric and unsaturated fatty acids may be used as active processing substance in polymers, in particular elastomers, at higher temperatures, in particular at higher vulcanization temperatures, than "Factice". They may be produced by a particularly elegant one-shot reaction.

摘要: The crosslinking of chlorinated polyethylene with 2,5-dimercapto-1,3,4-thiadiazole in the presence of a basic substance may be carried out easily and leads to improved vulcanizate properties if amido amines, for example tetraethylene pentamine distearate, are used as the basic substances.
摘要翻译: 在碱性物质存在下,氯代聚乙烯与2,5-二巯基-1,3,4-噻二唑的交联可以容易地进行,并且如果使用酰胺胺,例如四亚乙基五胺二硬脂酸酯作为 的基本物质。

摘要: The cross-linking of halogenated polymers such as chlorinated polyethylene with bis-(2,5-dimercapto-1,3,4-thiadiazole) in the presence of a basic substance may easily be carried out and leads to improved properties of the vulcanisate, in particular when amidamines such as, for example, tetraethylene pentamine distearate are used as basic substances.

摘要: An addition of 1 to 10% by weight and preferably 2 to 5% by weight, based on polyurethane rubber, of a fatty acid ester of pentaerythritol or a mixture of an alkane with a fatty acid to the polyurethane rubber mix eliminates the tendency towards sticking and improves the flow properties.
