Patent ID: 7342080

Claim:
A method of making a polymerizable composition comprising combining: a reactive fluorinated polyether; and a poly(meth)acryl compound under conditions sufficient to form a Michael-type adduct thereof, wherein the Michael-type adduct has at least one (meth)acryl group, wherein the reactive fluorinated polyether is described by the formula F(R f O) x QZ 1 R 1 NR 2 H or X(R f O) x QZ 1 R 1 NR 2 H wherein each R f independently represents a fluorinated alkylene group having from 1 to 6 carbon atoms; each x independently represents an integer greater than or equal to 2; each Q independently represents —CF 2 —, —CF(CF 3 )—, —CF 2 CF 2 —, —CF 2 CF 2 CF 2 —, —CF 2 CF(CF 3 )—, —CF(CF 3 )CF 2 —, —CF 2 CF 2 CH 2 —, —CF 2 CH 2 —, —CF 2 CF 2 C(═O)—, —CF 2 C(═O)—, —CF(CF 3 )C(═O)—, —CF(CF 3 )CH 2 —, an alkylene group having from 1 to 6 carbon atoms, or a heteroalkylene group having from 1 to 6 carbon atoms; Z 1 represents —S—, —O—, —NH—, or —NR 2 —; R 1 represents an alkylene, aralkylene, or heteroalkylene group; R 2 independently represents H or alkyl having from 1 to 6 carbon atoms; and X represents a polyvalent organic group.
