SIBR is a new-style rubber with an excellent combination of low rolling resistance and high wet skid resistance,and could be applied to making high performance tires.2,2-di (tetrahydrofuran-2-yl) propane(DTHFP),as a new kind of polar modifier for terpolymerization of styrene(St),isoprene(Ip) and butadiene (Bd),has not been reported.In this paper,the anionic terpolymerization of St,Ip,Bd was conducted with DTHFP as polar modifier,n-BuLi as initiator,hexane/cyclohexane as solvent at different temperatures.The kinetics of anionic copolymerization of St,Ip,Bd was investigated using the method of gas chromatography.
