Abstract: A method is disclosed for the manufacture of a bis(phthalimide), and polyetherimides derived therefrom, by reacting a phthalic anhydride having the formula with an organic diamine having the formula H2N—R—NH2, in a solvent, at a temperature from 140° C. to 220° C., and a pressure from 0 psig to 100 psig, in the presence or absence of a phase transfer catalyst, to form a bis(phthalimide) having the formula wherein a polyetherimide polymer is added either before or after the imidization reaction, to produce a bis(phthalimide) composition having a percent solids content of 18% to 30%, which bis(phthalimide) composition has a viscosity of less than 4000 cP at a shear rate of less than 30 sec−1 and temperaturefrom 140° C. to 180° C. as measured in a spindle viscometer.

Abstract: A method for producing a reactive intermediate composition, including: reacting a substituted phthalic anhydride of the formula (I) with a diamine of the formula H2N—R—NH2 in the presence of an aromatic dianhydride in an amount of 10 to 50 mole percent based on the total moles of anhydride functionality in the reaction; wherein the reacting is conducted in an aprotic solvent in a reactor, under conditions effective to produce the reactive intermediate composition; and wherein X comprises a halogen or a nitro group, and R comprises a C6-36 aromatic hydrocarbon group or a halogenated derivative thereof, a straight or branched chain C2-20 alkylene or a halogenated derivative thereof, or a C3-8 cycloalkylene or a halogenated derivative thereof.
