Patent number: 8609767Abstract: Toughened thermosetting resins comprising thermosetting resins and rubber particles having an average particle size in the range of 20 to 500nm. The toughened resins are obtained by mixing a fully vulcanized powdery rubber having an average particle size in the range of 20 to 500nm with thermosetting resin prepolymers and then curing them. The toughened thermosetting resins comprise rubber phases having a small, uniform and stable particle size, which results in a very significant toughening effect, especially when crazes rapidly grow (as in a standard Izod impact test). The toughened thermosetting resins are excellent in impact resistance, strength, modulus and heat resistance, and when appropriately toughened, the thermosetting resins can be enhanced in terms of impact strength, glass transition temperature and heat distortion temperature.Type: GrantFiled: October 8, 2002Date of Patent: December 17, 2013Assignees: China Petroleum and Chemical Corporation, Sinopec Beijing Research Institute of Chemical IndustryInventors: Fan Huang, Jinliang Qiao, Yiqun Liu, Xiaohong Zhang, Jianming Gao, Zhihai Song
