PURPOSE:To provide a compsn. flexible in the absence of plasticizers, excellent in transparency, heat resistance, weatherability, and low-temp. flexibility, by incorporating ethylene/vinyl acetate copolymer and particular block copolymer with vinyl chloride resin. CONSTITUTION:A thermoplastic resin compsn. which contains, as components, vinyl chloride resin, ethylene/vinyl acetate copolymer, and block copolymer of formula A-B-A (wherein A is a styrene polymer; B is a diene polymer). Said compsn. is transparent and excellent in flexibility, and has remarkably good heat resistance, thus being capable of use in a variety of fields where conventional resins are hardly usable so far, such as medical equipment (blood bag, infusion bag, catheter, blood circuit, circuit for artificial heart, surgical glove, etc.). In addn., it can also be used in laser, film for table ware package, tape substrate, wire coating materials, etc.
