The invention relates to a biodegradable copolymer. The technical result is that of producing a polymeric barrier material that exhibits improved strength and barrier properties and a high level of biodegradability. This technical result is achieved by the proposed biodegradable composite copolymer which includes cellulose acetate and cellulose propionate. The biodegradable composite copolymer further includes poly(glycerol succinate) (PGS), polyvinyl alcohol (PVA) and polyvinylpyrrolidone (PVP). The ingredients are taken in the following proportions: 5 wt% cellulose acetate; 5 wt% cellulose propionate; 5 wt% poly(glycerol succinate); 2 wt% polyvinyl alcohol; 2 wt% polyvinylpyrrolidone.
