Abstract：Two kinds of polyimide films were prepared based on the ODA and ODPA in NMP through two-step thermal or chemical imidization process and characterized by the cone and plate viscosimeter,GPC,FTIR,DSC,TGA and strain properties tests.The results showed that the films prepared from different imidizations had been totally transformed to polyimide films.The glass transition temperature,thermal decomposing temperature of the film from chemical imidization is higher than the one from thermal imidization.The strain tests showed that the film from thermal imidization had larger elongation at break,and the film from chemical imidization had larger tensile strength and elasticity modulus.
