Abstract

Polyetherimide sulfone resins can be prepared through the polymerization of dianhydrides, e.g., BPA-DA, with diamino substitutes materials, e.g., diamino diphenylsulfone (DDS) to make a polyetherimide sulfone polymer suitable for forming into a variety of articles. Articles made from these resins generally exhibit high strength, high heat resistance, transparency, solvent resistance, ignition and flame resistance. These resins are also typically good electrical insulators. Article forming methods include, e.g., injection molding, compression molding, thermoforming, extrusion into profiles, tubes, rods and films of various dimensions. The resins can be used to make fibers and filaments as well as coatings. The most preferred forming methods involve processing of molten polymer. The polyetherimide sulfone resin may also be formed into articles using solutions or powders. They may be used to form coatings and films by removal of solvent or fusing of powder.
