Abstract:
A method of manufacture of a polyetherimide copolymer composition includes contacting a substituted phthalic anhydride and an organic diamine in the presence of diphenyl sulfone, sulfolane, or a combination comprising at least one of the foregoing solvents at a temperature of greater than 130° C. to provide a bis(phthalimide) composition comprising diphenyl sulfone, sulfolane, or a combination comprising at least one of the foregoing solvents and a bis(phthalimide); and copolymerizing the bis(phthalimide), a substituted aromatic compound, and an alkali metal salt of a dihydroxy aromatic compound in the presence of diphenyl sulfone, sulfolane, or a combination comprising at least one of the foregoing to form a polyetherimide copolymer. The method does not require any catalyst either for the imidization or the polymerization.

Claim (Index 19):
The composition of  claim 18 , wherein the composition comprises a poly(arylene ether-sulfone), a poly(arylene ketone), or a copolymer thereof comprising structural units of the formula wherein\n Z is an aromatic C 6-24  monocyclic or polycyclic moiety optionally substituted with 1 to 6 C 1-8  alkyl groups, 1 to 8 halogen atoms, or a combination comprising at least one of the foregoing; \n each occurrence of G is independently \u2014C(O)\u2014 or \u2014SO 2 \u2014; and \n m is 1 or 2; and \n wherein\n the composition comprises one or more of \n greater than 0.1 parts per million of diphenyl sulfone, sulfolane, or a combination comprising at least one of the foregoing, or \n greater than 1 part per million of sodium or potassium, or a yellowness index of less than 300.
