摘要:
This application relates to miscible blends of biphenyl containing poly(aryl sulfones) and isopropylidene based polyimides. These blends are suitable for printed wiring board substrates, flexible printed circuit boards, electrical connectors and fabricated articles requiring heat and chemical resistance. A method for extruding these articles is taught.
