Abstract: We have reported the synthesis, morphological structure and single crystal structure of crystalline syndiotactic 1,2-polybutadiene. Now we want to study the effect of self-seeding nucleation on the crystallization behavior of it. In the report, the effects of self-seeding nucleation the crystallization behavior of syndiotactic 1,2-polybutadiene were studied by DSC and PLM techniques. The results indicated that the crystallization temperature of crystalline syndiotactic 1,2-polybutadiene increased obviously and the spherulite size decreased markedly after the process of self-seeding nucleation treatment.

Key words: Self-seeding nucleation, Syndiotactic 1,2-polybutadiene, Crystallization behavior
