ABSTRACT:
Novel thermoplastic compositions are provided comprising a blend of a polyindane resin and an engineering thermoplastic such as polyphenylene ethers, polysulfones, polycarbonates, polyether ether ketones, polyarylates, polyamides, polyimides and polyphenylene sulfides. Blends of thermoplastic block copolymers with polyindane resins are also provided. These blends provide improved processability with good physical properties including high impact strength and high heat distortion temperature.
