N2 - A kind of thermoplastic polyimide (TPI) was synthesized with 3, 3', 4, 4'-benzophenone-tetracarboxylic dianhydride (BTDA) and 4, 4'-oxydianiline (ODA) as monomers, the imidization process was a chemical one. The glass transition temperature of TPI was 275°C. TGA temperature at 5% mass loss was 560°C, this indicated that the TPI had good thermooxidative stability. Within the interested content range, TPI had good compatibility with LP-15, a semi-interpenetrating network (IPN) was formed between them. When the TPI content was 20% (mass fraction), the Tg value and impact strength were 13.5°C and 256% higher than those of LP-15 respectively, i.e. The modified resin exhibited simultaneous improvement in both toughness and Tg, which were very difficult to achieve by conventional toughing methods.
