摘要
以过氧化物酶为催化剂，在有机溶剂－水混合溶液中，合成了聚对苯二胺；研究了体系中有机溶剂的浓度对聚合产物分子量的影响，探讨了聚合产物的结构，并对其热稳定性进行了初步研究。
In this paper,the PTC (Positive Temperature Cofficient) effects of four kinds of carbon black,filled HDPE with different melting index were studied. We found that the smaller the melting index of HDPE,the higher the PTC intensity and the weaker the NTC effect of the material.After γ-ray irradiation, the four kinds of HDPE filled with carbon blacks have similar PTC curves. These are mainly due to the influence of molecular weight of HDPE.
