Sulfur copolymer compounds with styrene oligomer derivates have proved to be suitable yulcanizing agents. The content of oligomers of styrene in copolymeric sulfur was 15 % wt. and percentage quantity typed activator vulcanization was 2 %, 1 %, 0.5 % and 1 % wt. We used MgO and ZnO as activators of vulcanization. KEY WORDS: vulcanization, multicomponental copolymer sulfur, activator of vulcanization, styrene oligomers 1. INTRODUCTIONIn present time sulfur belongs to the most used vulcanization agents on vulcanization of unsaturated elastomers in rubber industry. For this reason we examined different manners, in order to obtain the best economic and technical reviews of sulfur for preparation of multicomponent copolymeric sulfur as vulcanization tanner. Here we present concrete results of preparations and use of multifunctional vulcanization agent produced by copolymeric cyclooctamer sulfur with oligomers of styrene and with di:fferent sort and quantity of vulcanization activators (MgO, ZnO). These copolymers proved to be suitable as new vulcanization agents. 2.
