Abstract:
A thermoplastic/rubber composite body comprisinga) a molding of at least one thermoplastic polymer selected from the group consisting of polyacetal and polyester,b) at least one functional element of at least one rubber copolymer, the rubber copolymer comprising a conjugated diene and a monoolefinic monomer,c) at least one reinforcing filler, andd) at least one crosslinking agent, and wherein the thermoplastic/rubber composite body is obtained byA) mixing the rubber copolymer with the reinforcing filler c) in the absence of crosslinking constituents, while heating at a temperature of 105 to 150.degree. C.,B) admixing the crosslinking agent d) at a temperature below 100.degree. C.,C) joining the resulting mixture from steps A) and B) with the molding of at least one thermoplastic polymer at 130 to 170.degree. C. by directly molding-on the functional element on the molding of at least one thermoplastic polymer by injection molding, coinjection on coextrusion the resulting mixture of steps A) and B) on the molding, andD) vulcanizing the rubber copolymer at 140 to 180.degree. C.
