IPC: C08G73/10
Abstract: A method of making a polyetherimide includes forming a monomer mixture comprising a bis(ether anhydride), a diamine and a volatile organic solvent; removing the volatile organic solvent to form a particulate solid; and melt polymerizing the particulate solid at a temperature 50 to 225° C. greater than the glass transition temperature of the polyetherimide in a single melt mixing device. The polyetherimide has an anhydride-amine stoichiometry and the standard deviation of anhydride-amine stoichiometry is less than 0.4 mol %.

Abstract: A method of manufacturing an isolated polyetherimide composition includes combining an as-synthesized polyetherimide comprising units of the formula (I) and a melt-stabilizing amount of a tri(C8-30 acyl) glyceride, an anhydride of the formula (II), or a combination comprising at least one of the foregoing, to provide a mixture; and isolating a polyetherimide composition from the mixture to provide the isolated polyetherimide composition having a change in complex viscosity measured over 30 minutes at 390° C., at a shear rate of 6.28 rad/seconds, strain=5%, and under nitrogen, from +15 to −20%, preferably from +10 to −20%, more preferably from +5 to −20%.

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.
