FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing high-molecular weight poly-N-vinylcaprolactam. Described is a method of producing high-molecular weight poly-N-vinylcaprolactam by radical polymerisation of vinyl caprolactam in presence of azo-isobutyric acid at reaction temperature 70 °C in water, characterised by that method includes adding to reaction system an activator in form of styrene in concentration 0.6×10-2-1.2×10-2 mol/l.
EFFECT: technical result is simplified process of producing high-molecular weight poly-N-vinylcaprolactam.
