FIELD: organic chemistry, chemical technology.
SUBSTANCE: invention relates to a method for separation of lactone-containing high-molecular compound comprising by-side alkyl chain and lactone-containing high-molecular compound comprising a by-side alkenyl chain. These lactone-containing high-molecular compounds have the general chemical structure. Method is carried out using strong cation-exchange resin comprising sulfoacid group that is treated preliminary with silver ions. Method provides effective separation of compounds that are similar by physical properties and without changes in structures of these compounds.
EFFECT: improved separating method.
