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。 In this paper, Ni-PB with different microstructure, different molecular weight, degree of branching and different degree of cross-linking was chosen to study its aggregation state at room temperature and its crystallization behavior at low temperature by electron microscope. The relationship between structure and performance is discussed.
