摘　　要：综述了橡胶增韧塑料机理研究的发展与现状 ,着重探讨了橡胶增韧机理中有关脆韧转变的定量研究 ,同时也讨论了分散相的形态参数、界面相容性和韧性测试条件以及分散相与基体的性能等因素对橡胶增韧塑料性能及增韧的影响 ,最后提出了橡胶增韧塑料研究的发展趋势。The recent progress and situation of study on the toughening mechanism of polymer toughened by rubber have been reviewed in this paper;especially the quantitative investigation on the brittle\|ductile transition of polymer/rubber blends has been emphasized.Also the influences of the morphology parameters of rubber particles,the compatibility of the interface between the rubber particles and polymer matrix,the testing conditions of toughness and the properties of rubber and matrix on the toughness and toughening mechanism of rubber toughened polymers have been discussed in detail.Finally,the trends of toughening of polymer by rubber in the future have been suggested.
