摘　　要：用结晶分级仪快速分析了不同聚烯烃树脂的结晶分布曲线特点及与分子链结构的关系。结晶分级法不仅可 用于聚烯烃树脂分子链结构的表征,还可用于对聚烯烃共混物的分析鉴别。该分析方法简便、快速,是表征聚烯烃结 构的有效手段。The crystallizability of HDPE,LDPE,LLDPE,PP and their blends were measured by crystallization analysis fractionation(CRYSTAF) .Co-relation between crystallizability and molecular structure was discussed. It was found that CRYSTAF can be used not only in characterization of polyolefin, but also in composition analysis of unknown polyolefin blends.
