摘　　要：传统的橡胶增韧聚合物机理研究在八十年代进一步发展、日臻完善。在此基础上开展了刚性粒子增初增强聚合物研究。本文回顾和讨论了橡胶增韧聚合物理论的新进展。在此基础上讨论了①刚性有机粒子增韧、②刚性无机粒子增韧、③刚性粒子和橡胶混杂填充增韧聚合物的基本概念、分析方法、界面的作用、脆韧转变的判据和机理。表明刚性粒子增韧聚合物是对橡胶增韧研究的补充和进一步发展，证实它是制备高韧性高刚度工程塑料新途径。In this review, the progress of the theories for rubber toughening polymer have been summarized.Then a new route to polymer toughening, including basic concept, analysis method, interfacial effect,criterion and mechanism for polymer toughening by rigid particles have been proposed and reviewed. It reveals that the cavetation damage is more important than the cold-drawing for polymer toughening by rigid particles. It also indicates that the theory of toughening by rigid particles is a supplement and a further progress for rubber-modified polymer. It is suggested that this theory is a realistic route of prepare high toughness and high stiffness engineering polymer alloys.
