FIELD: medicine.
SUBSTANCE: method of preparing a composition containing (meth)acrylamide polymer provides polymerisation of (meth)acrylamide and mixed monomer containing (meth)acrylamide. (Meth)acrylamide is produced by a biocatalytic reaction or an enzymatic process, and the biocatalyst contains the nitrile hydrase enzyme. An aqueous solution of (meth)acrylamide contains a cell material and/or ingredients of an enzymatic broth. The cell material and/or the ingredients of the enzymatic broth are not removed from the aqueous solution of (meth)acrylamide. Said method is used to prepare the composition applied as flocculants.
EFFECT: invention allows producing high-molecular water-soluble or swelling polymers.
