Abstract

Cellulose II (the structural component) was incorporated into latex of butadiene-acrylonitrile copolymer (the matrixial component) by coprecipitation of nitrilic latexcellulose xanthate mixture, according procedure developed in this Institute. According to different types of elastomeric compositions with 26%, 33% and 45% of acrylonitrile (monomers) and cellulose II up to 25 phr were evaluated. This study tries to correlate the rheometrical behaviour, which was estimated by cure parameters, with crosslink density values, which were obtained by swelling method using organic solvent. It was found that the amounts of both acrylonitrile and cellulose present in these several composites affect the cure results, and this fact suggests the presence of a rubber-filler interaction.
