用ＤＳＣ和ＷＡＸＤ方法研究了高密度聚乙烯／聚（乙烯丙烯辛烯－１）（ＨＤＰＥ／ＥＰＯ）共混体系的结晶性能。共混物的ＤＳＣ曲线皆呈单峰，表明共混体系形成了共晶。晶胞参数ａ及结晶度随共混物组成而变，进一步证明ＨＤＰＥ／ＥＰＯ共混体系的相容性．
The crystallization behavior of high density polyethylene / poly (ethylene-propylene-octene-1) (HDPE / EPO) blends was studied by DSC and WAXD methods. The DSC curves of the blends showed single peaks, indicating that the blends formed eutectic. The unit cell parameters a and degree of crystallinity change with the blend composition, further demonstrating the compatibility of HDPE / EPO blends.
