摘要
本文是一篇关于高聚物增韧机理的综述，在简要回顾传统增韧机理的基础上，详细介绍了近十年来高聚物增韧理论的进展。这些进展表明，８０年代以来增韧理论研究有了重大突破，主要表现为：增韧对象的重点已由脆性基体转移到韧性基体；增韧剂出现了弹性体向刚性粒子的扩展；机理性研究开始实现了由简单的定性解释向模型化、定量化的飞跃。
The paper is a review on toughening mechanism of polymer．After the traditional toughening mechanism is briefly reviewed，the new advances of tough-ening mechanisms are described in detail．These advances show that the study on toughening mechanism has been greatly developed since 1980＇s， which mainly displays that the object of study has been graduaily changed from brittle matrix to-wards ductile one;the toughening agent has been expanded from elastomer to-wards rigid particle； the study on toughening mechanisms has been advanced from qualitative demonstration towards quantization and modelling.
