阐述了环氧树脂的增韧方法和机理，对陶氏化学FORTEGRA 202环氧增韧剂在不同固化体系中的性能表现进行了研究。并与环氧胶粘剂中常用的端羧基丁腈橡胶（CTBN）或与环氧预聚的端羧基丁腈橡胶CTBN-Epoxy进行了性能对比。研究表明FORTEGRA 202环氧增韧剂除产品本身的低黏度所带来的配方调整空间更大的优势外，固化物还具有玻璃化转变温度高，拉剪强度更高，断裂韧性和透明度更好等优势。

The toughening technologies and mechanism of the thermoset epoxy resins were discussed and a new generation nano-toughener FORTEGRA 202 from Dow Chemical was studied in various hardener systems. Compared with carboxyl terminated butadieneacrylonitrile (CTBN) copolymer or the epoxy resin pre-reacted CTBN, FORTEGRA 202 epoxy toughener provided more space for formulation tuning due to its lower viscosity and the higher glass transition temperature (T ) for cured epoxy resins. Besides, it can provide better fracture toughness, higher adhesion and moreg transparent appearance due to its uniform nano size phase separation.
