Abstract
A sulfone adduct which comprises the reaction product of: ##STR1## and an unsaturated hydrocarbon polymer wherein X is an alkyl group selected from the group consisting of C.sub.n H.sub.2n +1, wherein n=1 to 18; X is an aryl group selected from the group consisting of C.sub.m H.sub.m-1 wherein m=6 and C.sub.m H.sub.m-2 Z wherein m=6 and Z is selected from the group consisting of OR', R', COOR'', NO.sub.2, Cl, Br, F and I where R', R' and R'' having about 1 to about 18 carbon atoms; wherein said unsaturated hydrocarbon polymer is selected from the group consisting of ethylene propylene terpolymers, ethylene diene copolymers, propylene diene copolymers, polyisoprene, butyl rubber, polybutadiene and styrenebutadiene, and styrene-isoprene random and block copolymers, polypropylenes and polyisobutylenes.
