PURPOSE:To provide a resin compsn. having high-frequency weldability and suitable for use as a material for medical instruments, by blending a thermoplastic styrene elastomer and an olefin resin with a vinyl chloride resin. CONSTITUTION:Pref. 10-100pts.wt. thermoplastic styrene elastomer and pref. 10-50pts.wt. olefin resin are blended with 100pts.wt. vinyl chloride resin. Olefin resins having a melt flow rate of 1.0g/10min or above are preferred. Examples of the vinyl chloride resins are polyvinyl chloride resin, a graft polymer obtd. from an ethylene/vinyl acetate copolymer and vinyl chloride and a copolymer of vinyl chloride with urethane. Examples of the thermoplastic styrene elastomers are a styrene/ethybutylene/styrene teleblock copolymer and a styrene/isoprene/ styrene teleblock copolymer. |
