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。
The structure of the polymer chain is linear or branched and the morphology of the polymer chain, the amount and length of the shear viscosity of the material, viscous flow activation energy, melt rupture phenomena such as rheological properties have a significant impact, and high Molding molecular material behavior is inseparable. This article discusses the relationship between the branching structure and the rheological properties of polymers by means of string talk. To understand, concord, and summarize the relationship between the polymer branching structure and rheology is conducive to make students more profoundly understand the relationship between the structure and properties of polymer materials in the course of “Polymer Rheology”, in-line polymer physics, polymerization Logistics science, polymer materials forming process series of professional knowledge of the course.
