Modification of Natural Rubber with Poly(diallyldimethylammonium chloride) and Polyvinyl Chloride

Resumo

The modification of natural rubber with poly(diallyldimethylammonium chloride) and polyvinyl chloride by mixing latexes was studied. It was established that coagulation with polyelectrolyte contributes to preservation of non-rubber components and reduction of the Mooney rubber viscosity, and the introduction of polyvinyl chloride increases the oil and gasoline resistance of the compositions. The revealed effects are explained by the influence of the natural rubber microstructure and polyvinyl chloride on the macroscopic properties of their blends.
