The vulcanization process of elastomeric blends based on chlorinated aromatic nitrile-butadiene rubber (SKN-40M) has been studied in the present work. The structural parameters (molecular weight, plasticity, rigidity, number of network chains, cross-linked molecules) in thermovulcanizates were investigated on an example of nitrile-butadiene rubber blend with polyvinyl chloride using viscometry and the sol-gel process.
