Abstract
A fluoropolymer having fluoropolyether linkages, at least two ester linkages, and hydrolyzable functional groups is represented by chemical structure (I): With respect to chemical structure (I), m is a number from 1 to 4 and n is a number from 10 to 60, each R1 is independently fluorine or CF3, R2 is an alkylene group, R3 is an alkylene group in which one or more hydrogens of the alkylene group are optionally substituted with fluorine, R4 is an alkyl group in which one or more hydrogens of the alkyl group are substituted with fluorine, R5 is an alkylene group in which at least one hydrogen of the alkylene group is substituted with a group comprising CF3, CF2H, or a hydrolyzable silyl group, and Z is a group represented by chemical structure (II), Methods of preparing the fluoropolymer and coating compositions containing the fluoropolymer are also included.
