| titleOfInvention | Manufacturing processes of bis (phthalimide) s and polyetherimides, and bis (phthalimide) s and polyetherimides formed therefrom |
| abstract | Process for the manufacture of a bis(phthalimide) composition, the process comprising catalyzing the imidation of a substituted phthalic anhydride and an organic diamine with a catalyst, in the presence of a solvent, the catalyst being selected from among quaternary ammonium salts, salts of quaternary phosphonium, guanidinium salts, pyridinium salts, imidazolium salts, and combinations thereof; wherein the substituted phthalic anhydride has a formula **Formula** and the organic diamine has a formula H2N-R-NH2; to provide the bis(phthalimide) composition comprising a catalyst residue, and a bis(phthalimide) of the formula **Formula*+ wherein, in the formulas above, X is selected from fluorine, chlorine, bromine, iodine, nitro, and combinations thereof, and R is selected from 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, -(C6H10)z-, where z is an integer from 1 to 4, an aromatic hydrocarbyl moiety having presents from 1 to 6 aromatic groups, and a divalent group of the formula**Formula** in which Q1 is a member selected from the group of a single bond, -O-, -S-, -C(O) -, -SO2-, -SO-, -CyH2y, where y is an integer from 1 to 5, and combinations thereof; wherein the conversion to the bis(phthalimide) is 99% complete, based on moles of substituted phthalic anhydride, in less than 6 hours, and wherein the bis(phthalimide) comprises less than or equal to 0.5 mole percent residual substituted phthalic anhydride, and less than or equal to 2 mole percent monoamine, based on the total moles of the substituted phthalic anhydride, the organic diamine, and a monofunctional reactant, if any. uses. |
