Abstract

The present invention relates to a method for processing a thermoplastic resin composition by extruding the composition through a nickel die to provide an extrudate having a low degree of surface roughness, said composition comprising PA1 (A) 100 parts by weight of a thermoplastic resin; PA1 (B) 0.01 to 1 part by weight of a hydroxy-functional diorganopolysiloxane having a number average molecular weight of at least 10,000; and PA1 (C) 0.001 to 1 part by weight of an organophosphorous compound.
