Abstract
Disclosed is (1) a mixture of fluoroalkyl alcohol-unsaturated carboxylic acid derivatives represented by the general formulae: CF(CF)(CH═CF)(CFCF)(CHCH)OCOCR═CHand CF(CF)(CF═CH)CF(CFCF)(CHCH)OCOCR═CH, wherein R is a hydrogen atom or a methyl group, n is an integer of 1 to 5, a is an integer of 1 to 4, b is an integer of 0 to 3, and c is an integer of 1 to 3; (2) a fluorine-containing polymer containing the mixture as a polymerization unit; and (3) a water- and oil-repellent comprising the fluorine-containing polymer as an active ingredient. The fluoroalkyl alcohol-unsaturated carboxylic acid derivatives are produced by an esterification reaction of a mixture of fluoroalkyl alcohols represented by the general formulae: CF(CF)(CH═CF)(CFCF)(CHCH)OH and CF(CF)(CF═CH)CF(CFCF), (CHCH)OH, with acrylic acid or methacrylic acid.
