Abstract

A fluorochemical graft copolymer comprising: a base polymer comprising polymerized units derived from monomers having terminal olefinic double bonds, having a moiety comprising a fluoroaliphatic group grafted thereto. Also disclosed are processes for preparing such fluorochemical graft copolymers, forming and annealing methods for enhancing the surface activity of such a graft copolymer, polymer blends comprising such a fluorochemical graft copolymer and a matrix polymer that is miscible with the base polymer, and a method for reducing the surface energy of a polymer comprising polymerized units derived from monomers having terminal olefinic double bonds.
