FIELD: chemistry.
SUBSTANCE: present invention relates to a method of extracting transition metals from polymer solutions. Described is a method of extracting transition metals from polymer solutions after atom transfer radical polymerisation (ATRP), characterised by that the transition metal compounds are precipitated by adding mercaptan or compounds having a thiol group as a precipitant and then removed by filtering.
EFFECT: efficient removal of transition metal complexes from polymer solutions.
