FIELD: chemistry.SUBSTANCE: claimed invention relates to obtaining acrylonitrile copolymers. Described is method for synthesis of acrylonitrilecopolymers, consisting in carrying out reaction of polymerisation of acrylonitrile with comonomers in carbon dioxide medium at temperature from 65 to 80°C, where itaconic acid or its derivatives is used as comonomers, characterised by the fact that thyols, determined by formula R-SH, where R represents saturated hydrocarbon radical with number of carbon atoms from 2 to 20, are added into initial reaction mixture.EFFECT: reduction of product polydispersity to required level.8 cl, 3 tbl, 21 ex |
