In order to obtain the optimized structure rubber,a novel miktoarm star styrene-butadiene rubber (MSSBR) 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-l,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.
