Abstract:
1. A fluorocarbon- and urethane-(meth)acryl-containing composition comprising a perfluoropolyether urethane having a perfluoropolyether moiety and a multi-(meth)acryl terminal group and having the formula: n ( p (A)QO(O)CHN)—R i —(NHC(O)XQR f ) m ; wherein R X is O, S or NR, wherein R is H or an alkyl group having 1 to 4 carbon; R each x is an integer greater than or equal to 2, and wherein d is an integer from 1 to 6; each Q is independently a connecting group having a valency of at least 2; A is a (meth)acryl functional group —XC(O)C(R m is at least 1; n is at least 1; p is 2 to 6; m+n is 2 to 10; wherein the perfluoropolyether urethane further comprises at least one unit attached to the R —(NHC(O)XQG), —(NCO), R —(NHC(O)XQD(QXC(O)NH) -D —(NHC(O)OQ(A) (NHC(O)XQ-R wherein G is selected from the group consisting of alkyl, aryl, alkaryl, aralkyl, fluoroalkyl, perfluoroalkyl; or a reactive group selected from (meth)acryl groups, vinyl groups, allyl groups and —Si(OR D is selected from the group consisting of alkylene, arylene, alkarylene, fluoroalkylene, perfluoroalkylene, and aralkylene; or said D group further containing heteroatoms selected from O, N, and S; D Q R wherein each R y is independently 2 or greater; u is independently 1 to 3; and t is 1-6.
