Claims7
A composition of matter for application to the hair or body of an animal comprising
- (a) a composition comprising
- (i) a copolymer comprising repeating A, B, and C monomers wherein:
- A is at least one free radically polymerizable acrylic or methacrylic acid ester of 1,1-dihydroperfluoroalkanols or homologs of 1,1-dihydroperfluoroalkanols, omegahydridofluoroalkanols, fluoroalkylsulfonamide alcohols, cyclic fluoroalkyl alcohols, and fluoroether alcohols present as up to 99% by weight of all monomer present;
- B is at least one reinforcing monomer copolymerizable with A, the amount by weight of a B monomer being from 0.01 to 30% of the total weight of all monomers in said copolymer;
- and
- C is a monomer present as from 0.01 to 50% by weight of all monomer present and having the general formula
- X(Y).sub.n Si(R).sub.3-m Z.sub.m
- wherein:
- X is a vinyl group copolymerizable with the A and B monomers;
- Y is a divalent linking group;
- R is hydrogen, lower alkyl, aryl, or alkoxy;
- Z is a monovalent siloxane polymeric moiety having a number average molecular weight of at least about 500 and is essentially unreactive under copolymerization conditions;
- n is zero or 1;
- m is an integer of from 1 to 3;
- and
- (ii) from 0 to about 500 parts by weight of compatible solvent or plasticizer per 10 parts copolymer as a solution, dispersion or emulsion in a liquid carrying medium;
- and
- (b) a medically effective amount of a medicament.
