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.

As composições thermoplastic da novela são fornecidas que compreendem uma mistura de uma resina do polyindane e de uma engenharia thermoplastic como ethers do polyphenylene, polysulfones, polycarbonates, cetonas do ether do polyether, polyarylates, polyamides, polyimides e sulfides do polyphenylene. As misturas de copolymers thermoplastic do bloco com resinas do polyindane são fornecidas também. Estas misturas fornecem o processability melhorado com as propriedades físicas boas including a força de impacto elevada e a alta temperatura da distorção de calor.
