ABSTRACT:
A crosslinked polysiloxane styrene/butadiene copolymer represented by the formula of FIG. 1 wherein m is a number of from about 2 to about 10; n is a number of from about 10 to about 1,000; k, l, o, p, q, r, s, t, u are weight fraction numbers totaling one with the sum of k+p+r+t being from about 0.35 to about 0.94; the sum of l+q+s+u being from about 0.05 to about 0.2 and o is from about 0.02 to about 0.5; R is CH.sub.2 CH(R'), alkyl-CR" C(O)O and alkylene-CR' C(O)O, where R' is an aromatic or substituted aromatic substituent and R" is hydrogen or an alkyl substituent.
