摘要:
Aromatic polyimide powder wherein a solid portion consisting of a highly heat resistant crystalline aromatic polyimide is covered with a coating layer of an amorphous polyimide, and a process for producing polyimide powder molded bodies by compression molding of the powder. The polyimide powder has satisfactory secondary molding workability, and molding thereof gives molded bodies which retain heat resistance and dimensional stability while having high mechanical strength and elongation.
