ACRYLONITRILE COPOLYMER PRODUCTION METHOD Russian patent published in 2017 - IPC C08F220/44 

FIELD: chemistry.

SUBSTANCE: process of preparation of the acrylonitrile copolymer is that a controlled radical polymerization of the monomer mixture comprising the following components, moll. %: 95-97 acrylonitrile, 2-4 methyl acrylate, 1-2 dimethylaconate, for 100-160 hours at a temperature of 50-80°C. The polymerisation is carried out in a solution of dimethylsulfoxide, under an argon atmosphere, using an initiator and a catalytic system. The components of the mixture are taken in the following molar ratio: 900-1900 of mentioned monomer mixture, 0.8-1 of carbon tetrachloride as initiator, 1-5 of copper (I) bromide, 2-15 tris [(2-pyridyl) methyl] ligand, 1-20 glucose as an activating agent.

EFFECT: invention makes it possible to obtain a copolymer having a number average molecular weight of more than 60 kD and a narrow molecular weight distribution to 1,32.
