Calcium lignosulfonate was incorporated into rubber compounds based on styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) in amounts ranging from 10 to 60 phr. A sulfur-based curing system a peroxide consisting of dicumyl combination with methacrylic acid zinc salt were used for cross-linking the compounds. The aim work investigate influence composition process, morphology, physical-mechanical dynamic-mechanical characteristics composites. achieved results showed that cured composites demonstrated higher cross-link density, which found not be influenced by content lignosulfonate. density sulfur-cured lower decreasing tendency increasing biopolymer. degree reflected elongation at break increase corresponding On other hand, peroxide-cured exhibited modulus M100 hardness. microscopic analysis revealed co-agent vulcanization contributed improvement adhesion between biopolymer resulting tensile strength equivalent caused restriction chain segments' mobility, due these glass transition temperature.
