Use of a perfluoroalkylvinyl polymer.

摘要

A perfluoroalkylvinyl copolymer comprising (a) repeating units of the formula: -CHRfCH2- (I) wherein Rf is a C5-C21 perfluoroalkyl group, and (b) repeating units of the formula: <CHEM> wherein Y is -OR<1>, -OCOR<1> or -COOR<1> and Z is a hydrogen atom or -COOR<2> in which R<1> and R<2> are, the same or different, a C1-C18 alkyl group with the proviso that when Y is -OR<1> or -OCOR<1>, Z is an hydrogen atom, and R is a C1-C18 alkyl group, which is useful as a mold release agent, a water- and oil-repellent and a non-tackifier.
