Novel copolymer and water- and oil-repellent comprising the same
First Claim
1. A fluorine-containing copolymer comprising(a) 40 to 90 % by weight of repeating units of a polymerizable compound having a C4 -C20 perfluoroalkyl group,(b) 5 to 50 % by weight of repeating units of at least one unsaturated ester selected from the group consisting of stearyl acrylate and stearyl methacrylate,(c) 5 to 50 % by weight of repeating units of at least one monomer selected from the group consisting of alkyl acrylate or methyacrylate having 2 to 8 carbon atoms in the alkyl group, cyclohexyl acrylate and cyclohexyl methacrylate.

Abstract
A fluorine-containing copolymer comprising
(a) 40 to 90% by weight of repeating units derived from a polymerizable compound having a C4 -C20 perfluoroalkyl group,
(b) 5 to 50% by weight of repeating units derived from at least one unsaturated ester selected from the group consisting of stearyl acrylate and stearyl methacrylate,
(c) 5 to 50% by weight of repeating units derived from at least one monomer selected from the group consisting of alkyl acrylate or methacrylate having 2 to 8 carbon atoms in the alkyl group, cyclohexylacrylate and cyclohexylmethacrylate, which is useful as an active component of a water- and oil-repellent.
