PURPOSE:To obtain a resin molding excellent in heat resistance and elasticity and useful for medical use, by irradiating a molding of a resin composition containing a vinyl chloride resin, an ethylene/vinyl acetate resin, and a poly(meth) acrylate with gamma-rays or electron beams. CONSTITUTION:A resin composition is formed from a resin composition containing 100pts.wt. vinyl chloride resin, 50-300pts.wt. ethylene/vinyl acetate resin (preferably, an ethylene/vinyl acetate/carbon monoxide copolymer), and 1-30pts. wt. poly(meth)acrylate [e.g., polyethylene glycol di(meth)acrylate] and irradiated with gamma-rays or electron beams to a gel fraction of 50-90% to produce a resin molding. This molding contains no plasticizer, is flexible and transparent, has excellent heat resistance and high elasticity and is suitable, especially for medical use, for example, blood bags, tubes for a blood circuit in artificial kidney dialysis, etc. |
