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.
