摘　　要：在125～135℃下氯化所得低度氯化聚乙烯(LCPE)的结晶度和熔点随其氯含量增加迅速下降;在80℃氯化所得LCPE的结晶度随其氯含量增加稍有降低,而其熔点基本不变;当氯化温度远低于原料HDPE的熔点时,局部过热是引起低熔点晶粒破坏、产物结晶度降低的主要原因。The crystallinity and melt point of low chlorinated poiyctnylcne (LCPE) decreasea rapidly with the increase of chloride content when the chlorination reaction carried out between 125℃ and 135℃. The crystallinity of LCPE decreased slowly with the increase of chloride content when chlorination temperature is 80 ℃, but the melt point remained as before. Local high temperatures were the reasons which caused the breakdown of crystal with low melt point and crystallinity decrease when the chlorination temperature was much lower than the melt point of the base resin HDPE.
