摘要： A method for preparing a thermoplastic elastomer is disclosed, said method comprising (I) mixing (A) a rheologically stable polyamide resin having a melting point or glass transition temperature of 25 DEG C to 275 DEG C, (B) a silicone base comprising (B') 100 parts by weight of a diorganopolysiloxane gum having a plasticity of at least 30 and having an average of at least 2 alkenyl radicals in its molecule and (B'') 5 to 200 parts by weight of a reinforcing filler, the weight ratio of said silicone base to said polyamide resin being greater than 35:65 to 85:15, (C) 0.1 to 5 parts by weight of a hindered phenol compound for each 100 parts by weight of said polyamide and said silicone base, (D) an organohydrido silicon compound which contains an average of at least 2 siliconbonded hydrogen groups in its molecule and (E) a hydrosilation catalyst, components (D) and (E) being present in an amount sufficient to cure said diorganopolysiloxane (B'); and (II) dynamically curing said diorganopolysiloxane (B'), wherein at least one property of the thermoplastic elastomer selected from tensile strength or elongation is at least 25 % greater than the respective property for a corresponding simple blend wherein said diorganopolysiloxane is not cured and said thermoplastic elastomer has an elongation of at least 25 %.
