【摘要】 本文选用不同微观结构、不同分子量、支化度及不同交联度的Ni-PB,用电子显微镜研究了其室温的聚集状态及低温下的结晶行为。讨论了其结构与性能的关系。更多还原

【Abstract】 This paper presents TEM study of aggregation and morphology of cis--1, 4--polybutadiene polymerized withNickel catalyst(Ni--PB) at different temperatures. The effects of microstructure, molecular weight, chain branch-ing and microgel content on crystallization behavour of Ni--PB were investigated. The relationship between struc-ture and mechanical properties of Ni--PB have heen discussed in detail.更多还原
