ABSTRACT:
Disclosed is a poly(ether-ketone) having an inherent viscosity of at least 0.4 and consisting of the repeating unit ##STR1## wherein each Ph is 1,4-phenylene. The poly(ether-ketone) is derived from two specific reactants, 1,3-bis-(4-phenoxybenzoyl)benzene and 4,4'-oxydibenzoic acid which may be reacted in the presence of methanesulfonic acid and phosphorus pentoxide.
