The present invention relates to a method for producing a new vinyl chloride resin graft copolymer, and in particular, its purpose is to provide a vinyl chloride resin graft copolymer with excellent oxygen permeability. Traditionally, polyvinyl chloride resin has excellent physical properties,
This resin has chemical properties, is resistant to aging, is highly durable, and is inexpensive, so it is used in large quantities across a wide range of fields.However, this resin has low oxygen permeability compared to other resins. It is not widely used in fields where such properties are required, such as packaging for fresh foods that require oxygen to maintain freshness. Furthermore, in the field of medical blood bags, there is a desire for a polyvinyl chloride resin material with good oxygen permeability to improve the preservation of blood, but no material has yet been proposed that satisfies this demand. The present inventors have conducted extensive research in view of these technical issues, and have discovered a new vinyl chloride resin graft copolymer that has performance (for example, excellent oxygen permeability) that conventional vinyl chloride resins do not have. Succeeded in developing a combination. That is, the present invention uses polyvinyl chloride resin from 50 to
95 parts by weight, general formula (R in the formula is a hydrogen atom or has 1 to 3 carbon atoms.
Q 1 and Q 2 are selected from alkyl groups having 1 to 5 carbon atoms, phenyl groups, and

100 parts by weight of the sample (resin), 50 parts by weight of di-2-ethylhexyl phthalate, 1.5 parts by weight of dioctyltin mercaptide, 1.0 parts by weight of calcium stearate, and 0.3 parts by weight of polyethylene wax were mixed into a 6-inch roll. The mixture was kneaded for 10 minutes at a roll temperature of 160°C. Next, this roll-kneaded product was press-molded at 170°C to form a sheet with a thickness of 0.5 mm, and the oxygen permeability of the sheet was examined using a fully automatic gas permeability tester.
