Open the CIPO recordAbstract From the Canadian patent
Disclosed are blends of (a) a polyetherimide and (b) an acrylonitrile-butadiene-styrene/polysulfone blend in which the latter ranges from 1 to 99 percent by weight of the composition. Blends of the present invention containing minor amounts of the polyetherimide component show improved flexural and tensile strength as well as a, higher heat distortion temperature over unmodified, acrylonitrile-butadiene-styrene/polysulfone blend. Additionally blends in which the polyetherimide is the major component show improved impact strengths as compared to the polyetherimide component itself.
