PURPOSE:To eliminate elution of a thermo-plastic agent into a contained object of blood or the like by compounding each specific amount of vinyl chloride/ ethylene copolymer of specific composition and ethylene/carbon monoxide (meta) alkyl ester acrylate copolymer. CONSTITUTION:In a mixing proportion of 8 to 70 pts.wt. ethylene to 100 pts.wt. vinyl chloride, when this mixture is copolymerized, the vinyl chloride is supplemented to a reaction system with the progress of copolymerization or the ethylene is removed from the reaction system, and the copolymerization is performed actually under the same mixing degree and pressure, compounding vinyl chloride/ethylene copolymer with a content of ethylene 2 to 25wt.%. A resin composition for a medical equipment is prepared by compounding 30 to 200 pts.wt. ethylene/carbon monoxide (meta) alkyl ester acrylate copolymer for 100 pts.wt. this vinyl chloride/ethylene copolymer. |
