Abstract
PURPOSE:To provide a gamma-ray resistant vinyl chloride polymer material composed mainly of a vinyl chloride copolymer produced by copolymerizing a specific amount of an alpha-olefin and having especially high resistance to discoloration with gamma-ray irradiation. CONSTITUTION:The objective gamma-ray resistant vinyl chloride polymer material is composed mainly of a copolymer produced e.g. by suspension polymerization of 100pts.wt. of vinyl chloride with 0.5-10pts.wt. of an alpha-olefin (preferably 4-30C alpha-olefin) in the presence of a suspension agent (e.g. methylcellulose), an initiator (e.g. dioctyl peroxy dicarbonate) and other additives in an aqueous medium. The material may be added with 5-80pts.wt. (based on 100pts.wt. of said polymer) of a plasticizer (e.g. dioctyl phthalate), 2-15pts.wt. of a stabilizer (e.g. epoxidized soybean oil or zinc stearate) and other additives.
