Abstract
A resin composition comprising PA1 (a) a vinyl chloride/ethylene copolymer having an ethylene content in the range of 3 to 12% by weight, an average degree of polymerization in the range of 700 to 2900 and a ratio of weight average molecular weight to number average molecular weight in the range of from 2.5:1 to 5.5:1, PA1 (b) an ethylene/carbon monoxide/vinyl acetate copolymer, and PA1 (c) a glycerin ester of a specific epoxidized aliphatic carboxylic acid. This resin composition is suitable for making medical devices, especially bags for storing transfusion fluids, receptacles for storing blood, and tubes for a blood circuit in artificial kidneys.
