Process for miscible blends of imide containing polymers with poly(aryl sulfones) |
摘要 |
A method for the preparation of miscible blends comprising biphenyl-containing poly(aryl sulfones) and polyimides is disclosed. The process comprises adding the monomeric polycarboxylic acid and aromatic diamine components of the polyimide to a suitable polyaryl sulfone in a vented extruder and melt-processing the resulting mixture, thereby polymerizing the monomers to form the polyimide component of the blend.
