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) :
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) :
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.
本发明公开了一种易于加工的聚酰亚胺,该聚酰亚胺在聚合物分子的末端被二价基封堵,该二价基来源于式(IV)所代表的二羧酸酐:
其中 Z 是二价基,选自以下组别:基本未被取代或被与胺或羧酸酐无反应活性的基取代的单芳香基,具有 5 至 15 个碳原子;通过直接键或桥接构件相互连接的缩合多芳香基或非缩合芳香基;具有由式 (III) 重复结构单元表示的基本骨架;以及 Z 是二价基,选自以下组别:基本未被取代或被与胺或羧酸酐无反应活性的基取代的单芳香基,具有 5 至 15 个碳原子;通过直接键或桥接构件相互连接的缩合多芳香基或非缩合芳香基;具有由式 (III) 重复结构单元表示的基本骨架:
其中 X 和 Y 为-O-或-CO-且彼此不同;聚酰亚胺的制备工艺;以及含有聚酰亚胺和纤维增强材料的树脂组合物。
