摘要
通过ＤＳＣ和ＷＡＸＤ研究了高密度聚乙烯／低密度聚乙烯／乙烯－醋酸乙烯共聚物（ＨＤＰＥ／ＬＤＰＥ／ＥＶＡ）三元共混体系的热行为和结晶性能。发现当ＨＤＰＥ含量小于４０％时，ＥＶＡ对ＬＤＰＥ起稀释剂作用，促进ＨＤＰＥ、ＬＤＰＥ的晶相分离，使ＨＤＰＥ、ＬＤＰＥ单独结晶．当ＨＤＰＥ含量高于４０％时，ＬＤＰＥ片晶进入ＨＤＰＥ晶相。形成与ＬＤＰＥ在片晶水平上的共晶。
The thermal and crystallization behaviour of HDPE/LDPE/EVA blends have been studied by DSC and WAXD technigues. The results showed that when HDPE content was less than 40%, the EVA as a diluent for the LDPE,promotes crystal phase separation of HDPE and LDPE; when the content of HDPE was more than 40%,LDPE may enter into HDPE crystalline regions,forming cocrystallite in the lamel lar regian.
