摘要

New copoly (ether-imide-sulfone) oligomers have been synthesized by solution polycondensation reaction of bis (p-chlorophenyl) sulfone with various imide bisphenols and 2, 2-bis (4-hydroxyphenyl)-propane (Bisphenol A). The Williamson polyetherification procedure has been chosen in view to ensure a partial hydrolysis of imide linkages into pendant potassium carboxylate groups. Chemical confirmation of the copolymers was ...
