Readily processable polyimide, preparation process of polyimide, and resin composition of polyimide. |
摘要 |
<p>Disclosed are a readily processable polyimide being blocked at the terminal of a polymer molecule with a divalent radical derived from dicarboxylic acid anhydride represented by the formula (IV): <CHEM> wherein Z is a divalent radical selected from the group consisting of a monoaromatic radical which is substantially unsubstituted or substituted with a radical having no reactivity with amine or carboxylic acid anhydride and has from 5 to 15 carbons atoms, condensed polyaromatic radical or noncondensed aromatic radical connected each other with a direct bond or a bridge member, and having a fundamental skeleton represented by recurring structural units of the formula (III ): <CHEM> wherein X and Y are -O- or -CO- and differ each other; preparation process of the polyimide; and resin composition containing the polyimide and fibrous reinforcement.</p> |
