　　The copolymerization of styrene (St)and butadiene(Bd) was initiated by a novel initiator system, C6H5*CH2Cl/MoCl3(OC8H17)2/PPh3 in toluene at 90 ℃, the mole ratio of C6H5*CH2Cl/MoCl3(OC8H17)2/PPh3/(St+Bd) was 1/1/3/200. Fig 1 presented the kinetics of copolymer ([M0],[M] was the content of monomer at the time of t=0 and t).……
