Patent ID: 8552106

Claim:
An aqueous dispersion which comprises: (I) a fluorine-containing polymer comprising repeating units derived from: (A) a monomer which comprises: (a) a fluorine-containing monomer of the formula: CH 2 ═C(X)COOYRf, wherein X is a hydrogen atom, a monovalent organic group, or a halogen atom, Y is a direct bond or a divalent organic group, and Rf is a fluoroalkyl group having 1 to 21 carbon atoms, wherein the monomer is polymerized in the presence of: (B) a functional organopolysiloxane selected from the group consisting of: (i) an amino-mercapto functional organopolysiloxane having the average formula: (R 2 SiO) a (RR N SiO) b (RR S SiO) c wherein a is 0-4000, b is 1-1000, c is 1-1000, R is independently a monovalent organic group, R N is a monovalent amino functional organic group, and R S is a monovalent mercapto functional organic group, (ii) a vinylamino functional organopolysiloxane having the average formula: (R 2 SiO) a (RR N SiO) b (RR V SiO) c wherein a is 0-4000, b is 1-1000, c is 1-1000, R is independently a monovalent organic group, R N is a monovalent amino functional organic group, and R V is a vinyl functional organic group, and (iii) a (meth)acrylamide-amino functional organopolysiloxane having the average formula: (R 2 SiO) a (RR N SiO) b (RR A SiO) c wherein a is 0-4000, b is 1-1000, c is 1-1000, R is independently a monovalent organic group, R N is a monovalent amino functional organic group, and R A is a (meth)acrylamide functional organic group, (II) water; and (III) an emulsifier consisting of a nonionic surfactant.
