【Abstract】 A HPVC SBR blended TPE was prepared by dynamic vulcanization.The effect of the single compatibilizer,the binary compatibilizer and the crosslink density on compatibility of HPVC SBR blend was investigated and predicted by using Hobbs′s method. The results show that the mechanical properties are significantly improved by adding the binary compatibilizer and the dynamic vulcanization, and the dynamic vulcanization plays an important role in improving the mechanical properties of the blends.更多还原
