Investigation of the Chain Structure and Crystalline of Chlorinated Polyethylene

Chain structure of the chlorinated polyethylene (CPE) synthesized by suspension process was characterized by 13CNMR to determine the content of the sequence length distribution of different kinds; The melting behavior was also studied by DSC. Crystalline and cocrystalline was found. With the result of the analysis, the effect of chlorine sequence distribution in chain of CPE on its crystalline and cocrystalline was discussed.
