Method for the preparation of thermoplastic resin composition

摘要

A method for preparing a thermoplastic resin composition, said method comprising hot-kneading, in the absence of a radical-generating catalyst, (A) 100 parts by weight of a thermoplastic resin; and (B) 0.1 to 200 parts by weight of an alkenyl-functional polyorganosiloxane filled with amorphous silica, wherein the weight ratio of said silica to said alkenyl-functional polyorganosiloxane is 0.01:100 to 50:100, whereby the polyorganosiloxane of component (B) is chemically bonded to resin (A).
