PURPOSE:To obtain a fluorine-contained copolymer useful as a water repellent or an oil repellent, or a resist material, etc. in high yield, by copolymerizing a specific fluorine-containing methacrylic acid ester with a styrenic monomer in the presence of a radical polymerization initiator. CONSTITUTION:(A) A fluorine-containing methacrylic acid ester shown by the formula I (R is alkyl group of hydrocarbon of fluorine) is copolymerized with (B) a styrenic monomer shown by the formula II (X is H, hydrocarbon alkyl, halogen, vinyl, amino, or hydroxyl group) in the presence of (C) a radical polymerization initiator, to give the aimed copolymer. A compound wherein R is CnH2n+1 (n is integer) or group shown by the formula III (m is 0-5 integer; Rf is 1-20C polyfluoroalkyl; R<1> is lower alkyl, H, or Rf) is preferable as the component A.
