Verfahren zur Herstellung von Verbundgegenständen aus Polyestern und Elastomeren

摘要

The object of the invention was to provide a process for the preparation of composite articles made from thermoplastic polyesters and a vulcanisate, in which, in contrast to the prior art, polyesters having an unimpaired processing behaviour are employed. The process found is characterised in that a) the polyester contains aliphatic double bonds and b) the vulcanisate is prepared under conventional vulcanisation conditions in contact with the hard component by vulcanisation of a rubber composition containing the following components: I. 100 parts by weight of a rubber, II. from 0 to 300 parts by weight of fillers, III. from 1 to 10 parts by weight of peroxidic vulcanising agents, IV. from 0 to 4 parts by weight of vulcanisation activators, V. from 0 to 150 parts by weight of plasticisers and VI. from 0.5 to 10 parts by weight of a silane of the formula X-R<1>-Si(OR<2>)3, where X contains an aliphatic double bond or an epoxide group. This process gives a strong composite bond.m
