摘要

A thermoplastic polymer comprising a fluorochemical ester composition of formula I: C<SUB>4</SUB>F<SUB>9</SUB>SO<SUB>2</SUB>N(Q<SUP>1</SUP>)(CH<SUB>2</SUB>)<SUB>a</SUB>O-C(O)-(CH<SUB>2</SUB>)<SUB>n</SUB>-C(O)O(CH<SUB>2</SUB>)<SUB>b</SUB>NQ<SUP>2</SUP>SO<SUB>2</SUB>C<SUB>4</SUB>F<SUB>9</SUB> (I) wherein Q<SUP>1</SUP> and Q<SUP>2 </SUP>which may be the same or different are each a hydrogen or an alkyl group of<I/>1 to 4 carbon atoms; a is an integer from 2 to 11; b is an integer from 2 to 11; and n is at least 10.
