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 2):
A method for the manufacture of a polyetherimide copolymer composition, the method comprising\n contacting a substituted phthalic anhydride and an organic diamine in the presence of diphenyl sulfone or sulfolane or a combination comprising at least one of the foregoing solvents at a temperature of greater than 130\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 or sulfolane or a combination comprising at least one of the foregoing solvent and a bis(phthalimide) of the formula and\n copolymerizing the bis(phthalimide), a substituted aromatic compound of the formula \n and an alkali metal salt of a dihydroxy aromatic compound of the formula\n MO\u2014Z\u2014OM \n in the presence of diphenyl sulfone or 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, X 1 , and X 2  are each independently fluoro, chloro, bromo, iodo, nitro, or a combination comprising at least one of the foregoing; \n R is an aromatic hydrocarbon group having 6 to 27 carbon atoms, a halogenated derivative thereof, a straight or branched chain alkylene group having 2 to 10 carbon atoms, a halogenated derivative thereof, a cycloalkylene group having 3 to 20 carbon atoms, a halogenated derivative thereof, \u2014(C 6 H 10 ) z \u2014 wherein z is an integer from 1 to 4, an aromatic hydrocarbyl moiety having from 1 to 6 aromatic groups, and a divalent group of the formula \n wherein Q 1  is \u2014O\u2014, \u2014S\u2014, \u2014C(O)\u2014, \u2014SO\u2014, \u2014C y H 2y \u2014 wherein y is an integer from 1 to 5, or a combination comprising at least one of the foregoing; M is an alkali metal; 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; G is \u2014C(O)\u2014 or \u2014SO 2 \u2014; and m is 1 or 2.
