FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing polyamide-6 by emulsion polymerisation of caprolactam. The method involves preparation of a reaction mass from caprolactam, water as an initiator and polyethylsiloxane liquid, heating, preliminary ageing, main ageing at 210-215°C, cooling and separating the formed granules, wherein the reaction mass is prepared first from caprolactam and water and heated to 210-215°C, preliminary ageing is carried out at 210-215°C for 6-7 hours, and the polyethylsiloxane liquid which is pre-heated to 210-215°C is added to the reaction mass before the main ageing which is carried out for 5-15 hours.
EFFECT: high quality of the end product and low power consumption.
