摘要:

AbstractCopolyimides were prepared by reacting 3,3′,4,4′‐benzophenone tetracarboxylic acid dianhydride (BPTD) with mixtures of various proportions of 3,3′‐sulfonylbis (phenyl isocyanate) (SDI) and 4,4′‐methylenebis (phenyl isocyanate) (MDI) in an aprotic polar solvent. The nature and properties of these copolyimides
