✦ Synopsis

Almtract--It is found that the interaction of geminal bis-sulphides with acyl(aroyl)peroxides forms systems which initiate polymerization in non-aqueous media. The mechanism of the reaction of benzoyl peroxide with bis(amylthio)methane was studied. The initiation is shown to result form the products of the interaction of the components.

Homopolymerization of styrene and methyl methacrylate was carried out a t 60-130Β°C in the presence of a mono-captodatively (cd) substituted ethane bearing nitrile and ethylsulfenyl substituents on the same carbon atom. It was found that the cd-ethane accelerated both styrene and methyl methacrylate
