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.
