Abstract:This article describes using FTIR, NMR, GPC, DSC and TEM technology to catalyze the rare earth and get new styrene-butadiene block copolymer, and carried out the characterization with micro-structure, composition, sequence, molecular weight and its distribution, thermal properties and characterization of micro-patterns, furthermore added 6.5%(wt) of the BS in the nickel butadiene rubber(BR 9000). It is found that this method can improve the tensile strength of vulcanized rubber and the wet skid resistance of BR.
