This study was focused on the effect of rubber polarity, rubber viscosity and molecular weight on mechanical properties of the blends.
Three types of rubbers were used: NR, epoxidized natural rubber (ENR25 and ENR50), and natural rubber grafted with poly(methyl methacrylate) (NR-gPMMA).
Effect of viscosity and molecular weight of NR, rubber mastication with a two-roll mill was investigated.
