has been synthesized in the presence of AlEt1.5Cl1.5 by using Mn2(CO)10-CBr4 initiation system. The GPC results indicated that there is no unreacted prepolymer in I purified by precipitation.The study of NMR showed that every block of polymer I has alternating structure. The dynamic mechanical properties of I measured by torsional braid method indicated that the polymer has two Tg
being 38℃ and 75℃
respectively. The transmission electron micrographs of I showed they have two phase stucture and the domain size indreases with increasing molecular weight of hard black.
