| Abstract: | Phenylethynyl) phthalic anhydride(4- PEPA) was synthesized by substitution reaction between4- bromo phthalic anhydride(4- BPA) and phenylacetylene under the catalysis of palladium system.A polyimide oligomer end- capped with4- PEPA (PEPA- PI) was also synthesized by condensating 3,4'- diaminodiphenyl ether(3,4'- DADPE) ,1,3- bis (3- aminophenoxy) benzene (BAPB) with 3,3',4,4'- benzophenone tetracarboxylic dianhydride (BTDA ) ,4- PEPA. Both 4- PEPA and PEPA- PI were characterized in this paper. |
