Features of process of polydiene sulfuric vulcanization in the presence of quaternary ammonium salts.

Kinetics and chemistry process of polydiene sulfuric vulcanization in the presence of quaternary ammonium salts (QAS), synthesized from accessible domestic raw material have been investigated. It was established, that QAS is not only the accelerator of vulcanization of low activity, but also can be used as the multifunctional additive in the absence in a mixture of the vulcanization activator. Unlike traditional accelerators of vulcanization, QAS, possibly, does not interact directly with rubber and does not crosslinked it. Nevertheless, QAS easily reacted with sulfur, that is an initial act of adduct formation - the polysulphidic agent of vulcanization that react with rubber with formation of active addition products, and in the further of vulcanization network.
