Method of extruding a polyolefin resin to facilitate processing of the resin

A method of extruding a polyolefin resin to facilitate processing of the resin, characterized in that a process aid is added to the resin, and said process aid comprises from 0.01 to 1.0 part by weight of a silicon bonded hydroxy-functional diorganopolysiloxane, having a number average molecular wei...

Zusammenfassung:A method of extruding a polyolefin resin to facilitate processing of the resin, characterized in that a process aid is added to the resin, and said process aid comprises from 0.01 to 1.0 part by weight of a silicon bonded hydroxy-functional diorganopolysiloxane, having a number average molecular weight of 38,000 to 1,000,000, per 100 parts by weight of said polyolefin resin, whereby the resulting ectrudate exhibits a reduced degree of sharkskin relative to the unmodified polyolefin.
