【Abstract】 A novel iontype photosensitive polyimide(PSPI) with thiophen acrylic acid as photosensitizer was prepared. It has a sensitivity of 2500 J/m2 and resolution of 1￣2 μm under irradiation with Hg lamp of 365 nm wavelength. The catalytic influence of tertiary amine on the imidization of poly(amic acid) during PSPI preparation has been discussed as well.更多还原
