Polyolefin composition containing diorganopolysiloxane process aid |
摘要 |
There is disclosed a polyolefin composition which can be extruded at relatively high rates to provide extrudate having a low surface roughness (sharkskin), said composition comprising (A) 100 parts by weight of a polyolefin resin; and (B) 0.01 to 1 part by weight of a hydroxy-functional diorganopolysiloxane process aid, said diorganopolysiloxane having a number average molecular weight of at least 10,000. In particularly preferred embodiments, a hydroxy-functional diorganopolysiloxane in combination with a low density polyethylene is used as a process aid for linear low density polyethylene.
