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 17):
The method of  claim 2 , the method comprising:\n 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 130\u00b0 C. to 250\u00b0 C., wherein the substituted phthalic anhydride has a formula and\n the organic diamine has a formula\n H 2 N\u2014R\u2014NH 2  \n \n 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) of the formula and\n copolymerizing the bis(phthalimide), a substituted aromatic compound of the formula \n and a disodium salt or a dipotassium salt of bisphenol A in the presence of diphenyl sulfone, sulfolane, or a combination comprising at least one of the foregoing solvents to form a polyetherimide copolymer comprising structural units of the formulas wherein in the foregoing formulae\n X is chloro; \n X 1  and X 2  are each independently chloro, fluoro, bromo, iodo, or nitro; \n R is m-phenylene, p-phenylene, p,p-diphenylether, or 4,4\u2032-diphenylsulfone; \n Z is \n and\n G is \u2014C(O)\u2014 or \u2014SO 2 \u2014.
