MULTICOMPONENT SYSTEM FOR PRODUCTION OF THERMOPLASTIC-RUBBER COMPOSITE MOULDINGS AND METHOD FOR PREPARING SAID MOULDINGS

摘要

Multicomponent system for production of thermoplastic-rubber composite mouldings comprising 1) a thermoplastic component and 2) a rubber component comprising a) one or more elastomers, where those elastomers of which 30% by weight or more are present in the rubber component, based on 100% by weight as the entirety of all of the elastomers of the rubber component, must be peroxidically vulcanizable, and b) two or more peroxidic crosslinking agents, where at least one peroxidic crosslinking agent whose decomposition temperature T1/2 (lh) is in the range from 70 to 130°C and at least one second peroxidic crosslinking agent whose decomposition temperature T1/2 (lh) is in the range from 120 to 160°C is used, where at least two peroxidic crosslinking agents are present whose difference in decomposition temperature T1/2 (lh) is at least 5°Cwhere the one or more thermoplastics present in the thermoplastic component 1) have been selected from the group consisting of one of more polyamides, polyimides, polyethers, polyesters, polyphenylene sulphide (PPS), polycarbonates-and combinations thereof.
