摘要
Silicon-containing poly(amide-imide)s have been synthesized by polycondensation reaction of various aromatic diamines with a dicarboxylic acid or a diacid dichloride containing the dimethylsilylene group and preformed imide Cycles. These Polymers are easily soluble in polar amidic solvents such as N-methylpyrrolidinone (NMP) or dimethylformamide (DMF) and can be cast into thin flexible films or coatings from such solutions. They show medium to high average molecular weights, high thermal stability, with initial decomposition temperature being above 400 degrees C and glass transition temperature in the range of 220-280 degrees C.
