摘要：
A fluorine-containing polymer which is an active component of a surface treatment agent having excellent water- and oil-repellency is constituted by a fluorine-containing polyether monomer of the formula: wherein Rf is a perfluoroalkyl group having 1 to 18 carbon atoms, R is hydrogen or a methyl group, A1 is a divalent linear or branched aliphatic group having 1 to 20 carbon atoms, A2 is a direct bond, or a divalent linear or branched aliphatic group having 1 to 10 carbon atoms which may have an ether linkage, X is a trivalent linear or branched aliphatic group having 2 to 5 carbon atoms, and n is from 1 to 100.
