Abstract:
A polymer having pendant fluoroalkylsulfide groups and pendant alkylsulfide groups comprising the reaction product of:a) a thiol of Formula IR.sub.f --(A).sub.d --B--S--H Iwherein:R.sub.f is a fully fluorinated straight or branched aliphatic radical of about 3 to about 14 carbon atoms optionally interrupted by at least one ether oxygen atom;A is a divalent radical selected from the group consisting of --SO.sub.2 N(R)--, --CON(R)--, --S--, and --SO.sub.2 -- wherein R is H or an alkyl radical of 1 to about 6 carbon atoms;d is 0 or 1; andB is a divalent linear hydrocarbon radical --C.sub.n H.sub.2n -- wherein n is from about 2 to about 12,b) a thiol of Formula IIX--R'--S--H IIwherein:X is H, OH, --COOM, or --SO.sub.3 M;M is H, Na, K, or NH.sub.4 ;R' is a difunctional alkyl group selected from the group consisting of --(CH.sub.2).sub.m --, --CH(COOH)--, and --CH.sub.2 --CH(COOH)--; a difunctional aromatic group --C.sub.6 H.sub.4 --; or a difunctional heterocyclic group --C.sub.5 NH.sub.3 --; andm is 1 to 18; andc) a polymer containing chlorine or bromine substituted on carbon, or a chlorinated or brominated paraffin of a maximum of 12 carbons and of a molecular weight of at least 250.
