MELT POLYMERIZATION METHOD FOR POLYETHERIMIDES

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 th...

Zusammenfassung:	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 %.
