| 摘 要： | The structure of polyimide from 1,4-bis (3', 4'-dicarboxyphenoxy) benzene and 4,4'-oxydianiline film specimens before and after hot stretching has been investigated by WAXD, DSC and FTIR. As evidenced by both the WAXD and DSC results, it could be believed that strain induced crystallization did take place after hot stretching. Meanwhile, shifting position and splitting of some band peaks existed on the FTIR spectrograms were explained in terms of the close packing of chains and the changes of inter-molecular charge-transfer interaction between imide groups and aromatic groups upon crystallization.
