Ternary copolymers of acrylonitrile with methylacrylate and itaconic acids and with derivatives of the latter — monomethyl ester (MME), monoethyl ester (MEE), monoamide, mono-n-octylamide, are synthesized in supercritical carbon dioxide medium. The morphology of the obtained copolymers is investigated using scanning electron microscopy. Copolymers with itaconic acid, its MME and MEE form regular particles of about 1 μm size with no addition of any stabilizer.
