POLY(ARYL ETHER KETONE)S CONTAINING THE 2-NAPHTHALENYL MOIETY

Amorphous, thermally stable poly(aryl ether ketone)s (PAKs) were prepared by the condensation polymerization of the novel dihalide 1,2-bis(4-fluorobenzoyl)-3,6-diphenyl-4,5-bis(2-naphthalenyl)-benzene and biphenols in dipolar aprotic solvents in the presence of potassium carbonate. The presence of pendant 2-naphthalenyl moieties was found to have no deleterious effects on the thermal stabilities or solubilities of the PAKs. The properties of these polymers are compared to those of PAKs prepared previously in this laboratory. Evidence of a single electron transfer reaction between hydroquinone and the novel dihalide involving the pendant 2-naphthalenyl moieties was found and was investigated through model reactions.
