veratroyl, p-bromobenzoyl, p-phenylbenzoyl, p-benzoylbenzoyl, p-methylsulfonylbenzoyl, p(N,N-dimethylsulfonamido)-benzoyl and -naphthoyl disulfides are promoters of the emulsion copolymerization of butadiene and styrene, but exhibit little effect on the polymer properties. Furoyl, phenyl, p-chlorophenyl and p-bromophenyl disulfides are neither promoters nor modifiers.
