ABSTRACT:
Process for producing composite articles made of polyesters and elastomers. Composite articles made of a thermoplastic polyester and a vulcanizate are to be produced. These articles are obtained by producing the vulcanizate under conventional vulcanization conditions in contact with the hard component by vulcanization of a rubber composition which contains 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 vulcanization agents,
IV. From 0 to 4 parts by weight of vulcanization activators and
V. From 0 to 150 parts by weight of plasticizers, where
a) the hard and/or the soft component, as desired, additionally contains from 0.5 to 12 parts by weight of a difunctional or polyfunctional maleimide and
b) in the case of the hard component containing no difunctional or polyfunctional maleimide, the rubber possesses carboxyl or acid anhydride groups.
A strong composite is obtained by this process.
