  • Patent number: 8609767
    Abstract: 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.

  • Patent number: 8598273
    Abstract: Polymer electrolytes offer increased safety and stability as compared to liquid electrolytes, yet there are a number of new challenges that polymer electrolytes introduce. A polymer electrolyte, as disclosed herein, is a block copolymer that has a block that provides mechanical strength and a novel, ionically-conductive polymer block with a backbone that is both highly flexible and highly conductive with high conductivity pendant chains attached, thus increasing the concentration of lithium coordination sites and improving ionic conductivity. Previous strategies for comb-type conductive polymers have focused on attaching either conductive pendant chains to a flexible non-conductive backbone or conductive pendant groups to a marginally flexible conductive backbone.
