FIELD: chemistry.
SUBSTANCE: proposed method of producing polivinilphosphinic acid from red phosphorus and acetylene in the potassium hydroxide/DMSO system under heating is characterized in that the reaction with red phosphorus is carried out at atmospheric pressure in an acetylene stream at a temperature of 105-115°C for 3 hours, without adding water to the reaction mixture and at a molar ratio of the reagents to red phosphorus: potassium hydroxide hemihydrate: DMSO equal to 0.10:0.154:2.11.
EFFECT: new improved method of producing organophosphorus polymer, which allows to increase the yield of the desired product.
