| titleOfInvention | Low-moisture-absorption high-heat-resistance polyimide toughening polymer and preparation method thereof |
| abstract | The invention discloses a low-moisture-absorption and high-heat-resistance polyimide toughening polymer, wherein a molecular chain of the polymer comprises repeating structural units shown in a formula (I) and a formula (II). The polyimide toughening particles prepared by the invention have the characteristics of uniform particle size distribution, low water absorption, high heat-resistant temperature and the like, can simultaneously meet the requirements of low moisture absorption and high heat resistance, and have wide application prospects. |
