Chemical interaction between epoxidized natural rubber and silica: Studies on cure characteristics and low‐temperature dynamic mechanical properties

摘要

AbstractThe unusual reinforcement mechanism exhibited by silica in epoxidized natural rubber (ENR) may be attributed to the specific chemical interaction or the chemical cross‐linking taking place between silica and the epoxy groups while heating the mix. Evidence for the higher interaction is established through rheometric studies conducted at 180°C and changes in the dynamic mechanical characteristics studied over a wide temperature range using a dynamic viscoelastometer for the heated and unheated silica‐filled m
