CRYSTALLIZATION AND MORPHOLOGY OF HIGH CIS 1,4-POLYBUTADIENE
高顺式-1,4-聚丁二烯的结晶形态研究

Cis 1,4-polybutadiene synthesized by rare-earth catalyst has high cis content, high degree of molecular reqularity and low degree of branching. The crystallization and morphology of the polymer were studied at low temperature with electron microscope-It was observed that the morphology and growth rate of spherulites are affected by the degree of molecular regularith and conditions of crystallization.
