Abstract:
A method of manufacture of a polyetherimide 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 polymerizing the bis(phthalimide) 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. The method does not require any catalyst either for the imidization or the polymerization.

Claim (Index 4):
The method of  claim 1 , further comprising\n determining the stoichiometric molar ratio of the substituted phthalic anhydride to the organic diamine during the imidization of the substituted phthalic anhydride and the organic diamine; and optionally adjusting the stoichiometric molar ratio by adding additional substituted phthalic anhydride or organic diamine.
