Abstract:
A method for preparing a thermoplastic elastomer, said method comprising:(I) mixing (A) a Theologically stable polyamide resin having a melting point or glass transition temperature of 25Â° C. to 275Â° C., (B) a silicone base comprising (Bâ€²) 100 parts by weight of a diorganopolysiloxane gum having a plasticity of at least 30 and having an average of at least 2 alkenyl groups in its molecule and optionally, (Bâ€³) 5 to 200 parts by weight of a reinforcing filler, the weight ratio of said silicone base to said polyamide resin is from 35:65 to 85:15, (C) a compatibilizer selected from glycidyl ester polymers or organofunctional grafted polyolefins, (D) an organohydrido silicon compound which contains an average of at least 2 silicon-bonded hydrogen groups in its molecule and (E) a hydrosilation catalyst, components (D) and (E) being present in an amount sufficient to cure said diorganopolysiloxane (Bâ€²); and (II) dynamically vulcanizing said diorganopolysiloxane (Bâ€²).
