Studies on a New Vulcanization Syste

Studies on the chemistry of vulcanization” play a central role in the efforts to achieve better product performance from natural and synthetic rubbers. They provide rubber technologists with an increasingly realistic picture of molecular framework of vulcanizates, from which relation between physical properties and chemical constitution may be deduced. Moreover, these studies are also aimed at the understanding of the vulcanization process, in sufficiently advanced chemical mechanistic terms, so that the effect of changes on vulcanizate structure can rationally be predicted.“ The study of accelerator activity ofthe binary system containing ATU with TMTD, and with MBTS in sulphur vulcanization of dry natural rubber using standard procedures for compounding and vulcanization is described in the third chapter. The study of the gum vulcanizates form part I of this chapter The behaviour of the experimental mixes were compared with those of the controls containing thiourea; diphenyl guanidine
