Abstract

A series of polyimide was prepared based on 3,3',4,4'-biphenyltetra carboxylic dianhydride (BPDA) with noncoplanar, 1,2,4,5-benzenetetracarboxylicanhydride (PMDA) and 4,4'-diaminodiphenyl ether (ODA). The effect of the polymer structure and imidization temperature on the thermal stability and mechanical properties of polyimide was investigated. The results showed that the toughness of polyimide were effectively improved as the noncoplanar structure was introduced into polyimide molecular chain. The mechanical properties of polyimide reached the maximun at imidization temperature of 300 . The tensile strength and elongation at break of polyimide were 51.84 MPa and 13.63% respectively, and the high heat resistance was excellent.
