Claim:
1. A fluorine-containing polymer prepared by polymerizing a monomer comprising: (I) a polyfluoroalkyl group-containing acrylate which is substituted at the alpha-position with a monovalent organic group other than a methyl, or with a halogen atom, wherein the polyfluoroalkyl group has 1 to 6 carbon atoms, in the presence of: (II) a blocked isocyanate compound, wherein a blocking agent in the isocyanate compound (II) is a pyrazole or an active methylene-containing compound, and (III) a functional organopolysiloxane, wherein the functional organopolysiloxane (III) is a functional organopolysiloxane comprising siloxy units having the average formula: wherein the functional organopolysiloxane bonds to the fluorine-containing polymer through a functional organic group, and wherein the blocked isocyanate compound is a compound having a blocked isocyanate group and no polymerizible unsaturated group.
