摘要: 本工作主要利用DSC、x-射线衍射、小角激光光散射以及偏光显微镜等方法,对天然橡胶/低密度聚乙烯共混体系(NR/LDPE)中LDPE的晶体结构、结晶度、球晶尺寸和形态、微晶尺寸、成核过程以及结晶动力学等方面进行了研究,得到了一些有意义的结果。

Abstract: Some methods were used to invetigate the crystalline behavior of low density polyethy-lene(LDPE) in natural rubber/LDPE blends. It was found that NR acted as a nucleationagent in the crystallization of LDPE. The crystallization rate of LDPE increased with theaddition of NR.
