In order to obtain the optimized structure rubber, a novel miktoarm star styrene-butadiene rubber (MS-SBR) was initiated by a multifunctional macromolecular initiator with polydiene arm and Sn-C bond. The properties of MS-SBR were investigated with respect to the morphology, mechanical properties, and dynamic viscoelasticity in comparison with those of the blends, natural rubber (NR)/star styrene-butadiene random rubber(S-SBR) blend rubber and cis-1,4-polybutadiene rubber (cis-BR)/S-SBR blend rubber. The samples were analyzed using transmission electron microscopy (TEM), dynamic mechanical thermal analyzer (DMTA), and mechanical properties test. The analysis results show that MS-SBR possesses the desired combination of low rolling resistance and high antiskid resistance, and is promising for application in high performance tire tread. 相似文献
