摘　　要：综述了聚乙烯(PE)树脂的流变行为与其相对分子质量、相对分子质量分布、支化结构、加工性能、制品性能的关系,介绍了用流变手段及参数表征PE树脂分子结构的方法。建议加大PE树脂流变行为的研究力度,为PE树脂的产品开发与推广应用提供技术支持。This paper reviewed the relationship between rheological behavior and relative molecular mass and its distribution, branching structure, processing performance and product properties of polyethylene（PE） resins. The methods for characterizing PE resins＇ structure by theological measurement and parameters were introduced. The authors suggested that the study on PE resins＇ theological behavior should be strengthened in order to provide technological support for product development and application of PE resin.

关 键 词：聚乙烯 流变行为 相对分子质量 支化
