Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: used are films made of glycosaminoglycan conjugates with 4- or 5-aminosalicylic acids or alginate conjugates with 4- or 5-aminosalicylic acids or intermixed conjugates or mixed conjugates and at least one polymer chosen from group including carboxymethyl cellulose, glycosaminoglycan, alginate, gelatine, albumin with salicylate content not less than 50%. Specified mixtures are treated with 2-20% iron (III) chloride solution at room temperature within 1-5 minutes. Surface complex lowers water- and biological liquids solubility of the film. ^ EFFECT: prolonged of biomaterial activity is provided. ^ 10 ex
