ABSTRACT:
Blends comprising a polyether sulfone and an imide-containing copolymer of sulfonyl bis(phthalic anhydride), 1,4-bis(p-aminocumyl) benzene and at least one of a selected group of diamine comonomers. The blends display a unique combination of excellent mechanical and thermal properties as well as good solubility and easy melt-fabricability; in addition, the resin components are compatible, and many compositions are unexpectedly miscible.
