摘要

An imide ring-performed dicarboxylic acid bearing one hexafluoroisopropylidene and two ether linkages between aromatic rings, 2,2-bis[4-(4-trimellitimidophenoxy)phenyl]hexafluoropropane (II), was prepared from the condensation of 2,2-bis[4-(4-aminophenoxy)phenyl]hexaluoropropane and trimellitic anhydride. Anovel series of poly(amide-imide)s having inherent viscosities of 0.72～1.86 dL g~(-1) was prepared by the triphenyl phosphite-activated polycondensation fromt he diimide-diacid (II) with various aromatic diamines in a medium consisting of N-methyl-2-pyrolidone, pyridine, and calcium chloride. Several of the resulting polymers were soluble in polar amide solvents, and their solutions could be cast into transparent, thin, flexible films having good tensile properties and high thermal stability. The 10% weight loss temperatures were all above 495deg C in air or nitrogen atmosphere, and the glass transition temperatures were in the rnage of 237deg-276deg C.
