  • Polyetherimide-polycarbonate blends
    Patent number: 4548997
    Abstract: Disclosed are blends of (a) a polyetherimide and (b) a thermoplastic polycarbonate. The blends exhibit a higher heat distortion temperature and an improved flexural strength and tensile strength over the polycarbonate component alone and have a higher impact strength than that associated with the polyetherimide component of the blends. In addition, the blends may exhibit good flame resistance.

  • Melt polymerization method for making polyetherimides
    Patent number: 4073773
    Abstract: An improved extrusion melt polymerization method for continuously making polyetherimides is disclosed wherein a mixture of an organic diamine and an aromatic bis(ether anhydride) is continuously fed through an inlet opening into a screw extruder having a second opening downstream from the inlet opening. The mixture is passed through a first extruder zone maintained at a low temperature to a zone where the mixture is melted and water of reaction is continuously removed through the second opening. A melt seal may be employed between the second opening and a third opening through which water of reaction may be removed under vacuum.
