The present invention is polymerized from starch and vinyl monomer, wherein the weight ratio of starch: vinyl monomer of the copolymer is 30:70 to 90:10, and the vinyl monomer is 10:90 to 90:10 of aromatic vinyl monomer and aliphatic vinyl monomer. Starch-vinyl copolymer comprising a weight ratio of, to a starch-vinyl copolymer comprising an aqueous emulsion and a method for producing the same, the copolymer is biodegradable by using a reproducible starch, environmentally friendly, inexpensive In addition, the reduction in adhesion and gloss and whiteness are not only improved, but also the repairability and the rigidity may be industrially widely used. |
