Abstract
Described herein are random poly(etherimide) containing ether-imide units and aryl ether and/or aryl ether ketone units. These copolymers are produced by the reaction of the appropriate activated dinitro- and/or dihalobenzenoid aromatic compounds with diphenols, and/or by the self condensation of halophenols and/or nitrophenols, whose halogen atom and nitro group are activated towards nucleophilic substitution reactions.
