摘要

高分子链结构为直链型或支化型以及高分子支链的形态、多寡和长度对材料的剪切黏度、黏流活化能、熔体破裂现象等流变性能有显著影响，且与高分子材料成型加工行为密不可分。本文以串讲方式讨论了高分子材料支化结构与流变性能之间的联系。理解、串并、归纳和总结高分子支化结构与流变性之间的联系有利于使学生更加深刻领会《聚合物流变学》课程中高分子材料结构与性能间的关系，串联高分子物理、聚合物流变学、高分子材料成型加工系列专业课程知识。

Abstract

Branched structure has a significant influence on polymer rheological properties such as shear viscosity

viscous flow activation energy and melt fracture phenomenon. In this paper the relationship between branched structure of polymer and rheological properties was summarized. Understanding the relationship between branched structure of polymer and rheological properties would help students to grasp the structure-property relationship of polymer materials and series- connect the knowledge of polymer physics

polymer rheology and polymer processing.
