POLYOLEFINE PROCESSING AIDS BASED ON FUNCTIONALIZED SILICONS

Abstract

A composition comprising: (a) a polyolefin; and (b) 0.01 to 50 wt.% of a functionalized poly(dialkylsiloxane) copolymer having the formula where R is an alkyl group having 1 to 8 carbon atoms, R1 and R2 are the same or different and are either alkyl or poly(oxyalkylene) chains terminated with a polar or charged functional group selected from an alcohol, an ammonium ion or a phosphate; where m is from 1 to 15,000, n is from 1 to 15,000 and p is from 0 to 5,000, and where the molecular weight of the functionalized poly(dialkylsiloxane) copolymer is greater than 10,000 g / mol.
