摘要: 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.

Abstract: The miscibility and cocrystallization of blends consisted of high density polyethy-lene(HDPE) and (ethylene-propylene-octene-1)copolymer (EPO) has been studied by DSC and WAXD methods, Only a single melting or cooling peak was found in DSC curves for all blends, showing an existence of cocrystalline interaction, The crystal parameter and crystallinity of the blends are in dependence of the composition of the blends, revealing the compatibility of the system.

Key words: high density polyethylene, poly (ethylene-propylene-octene), blend, cocrystalline
