Polybutadiene-b-polyisoprene diblock copolymer(PB-b-PI) was synthesized using anionic polymerization initiated by n-butyllithium.PB segment in it was then uniquely hydrogenated in the presence of cobalt 2-ethylhexanoate/triethylaluminium catalyst,giving poly ethylene-b-polyisoprene diblock copolymer(PE-b-PI).The two diblock copolymers were characterized by infrared analysis,GPC,viscosity,DSC,x-ray diffraction and dynamic mechanical measurements.
