摘要

Abstract

The soluble photosensitive polyimides were synthesized by the copolymerization of 3

3'-diaminochalcone(mDAC)

bis(3-aminophenyl)-3

5-bis(trifluoromethyl)phenyl phosphine oxide(mDA6FPPO)and 4

4’-(hexafluoroisopropylidene)-diphthalic anhydride(6FDA)．The polymers were characterized by FR-IR spectrum

and the properties of polymers were also discussed. The results show that the polyimides have excellent solubility in conventional organic solvents such as NMP

DMF

THF and acetone．The Tgs of polyimides are ranged in 256℃～277℃．The polymers are stable up to over 400℃ and the residual weights at 800℃ are between 46％～50％．The resulting polyimides have good adhesive properties

and they were found to increase with increasing the mDA6FPPO content．The photosensitivity of the polymers was investigated by observations of UV—Vis spectral changes during UV irradiatino.
