PURPOSE: To prepare a composition having excellent flexbility and transparency, free of hemolytic property and cytotoxicity, and suitable for a blood bag, by compounding a vinyl chloride resin with the copolymer of ethylene, CO and vinyl acetate, and fine powder of magnesium hydroxide and calcium hydroxide. n CONSTITUTION: The objective composition is prepared by compounding (A) 100pts.wt. of a vinyl chloride resin with (B) 5W200pts. of an ethylene-carbon monoxide-vinyl acetate copolymer obtained by the copolymerization of 1pt. of ethylene with 0.03W0.5pt of carbon monoxide and 0.1W0.9pt. of vinyl acetate, and (C) 0.1W10pts. of magnesium hydroxide fine powder and/or calcium hydroxide fine powder having particle diameter of ≤50μ. n COPYRIGHT: (C)1982,JPO&Japio |
