ABSTRACT:
Aromatic polyetherimides can be blended with aromatic alkyl methacrylate polymers to give transparent, single phase and completely miscible materials at all compositions. Such blends, which exhibit only one glass transition, are endowed with improved workability, ease of processing and toughness compared to the polyetherimide alone as well as improved heat distortion, modulus and tensile strength as compared to the methacrylate alone. Aromatic polycarbonates, which are ordinarily immiscible with aromatic polyetherimides, can be compatibilized into single phase blends after the addition of a polyaromatic alkyl methacrylate.
