摘要

The 2,2-bis[4- (4-aminophenoxy)phenyl] propane (BAPP), as a monomer to prepare polyimide, wasrnsynthesized via the nucleophilic substitution reaction. FTIR and NMR were used to confirm thernstructure of the compound. Polyimide was prepared by BAPP reacting with 3,3',4,4' -oxydiphthalicrndianhydride (ODPA) via a two-step method. The films were measured by means of FTIR, DSC, andrnDMA.
