wheat starch and vinyl acetate are evenly mixed and irradiated with 60Co without solvent to obtain most of the ungrafted homopolymers. if the mixture of methanol and water is 3:2 (volume ratio), 15% starch grafted vinyl acetate copolymer can be obtained with a grafting rate of 40%. The starch and vinyl acetate were irradiated in advance, and then mixed and reacted to obtain starch grafted vinyl acetate copolymer, but the conversion rate was low.
