Blends of acrylonitrile-butadiene-styrene/polysulfone blends with polyetherimides

摘要

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.
