MIXTURE OF FLUOROALKYL ALCOHOL-UNSATURATED CARBOXYLIC ACID DERIVATIVES, POLYMER OF THE DERIVATIVES, AND WATER REPELLENT OIL REPELLENT AGENT CONTAINING THE POLYMER AS ACTIVE INGREDIENT

摘要

Disclosed is (1) a mixture of fluoroalkyl alcohol-unsaturated carboxylic acid derivatives represented by the general formulae: CF 3 (CF 2 ) n (CH=CF) a (CF 2 CF 2 ) b (CH 2 CH 2 ) c OCOCR=CH 2 and CF 3 (CF 2 ) n-1 (CF=CH) a CF 2 (CF 2 CF 2 ) b (CH 2 CH 2 ) c OCOCR=CH 2 , 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 3 (CF 2 ) n (CH=CF) a (CF 2 CF 2 ) b (CH 2 CH 2 ) c OH and CF 3 (CF 2 ) n-1 (CF=CH) a CF 2 (CF 2 CF 2 ) b (CH 2 CH 2 ) c OH, with acrylic acid or methacrylic acid.
