A study of the morphology of acrylonitrile-methylacrylateitaconic acid/itaconic acid derivative copolymers synthesized in a supercritical carbon dioxide medium

摘要

Ternary copolymers of acrylonitrile with methylacrylate, itaconic acid (IA), and its derivatives, namely, monomethyl ester (MME), monoethyl ester (MEE), monoamide, and mono-n-octylamide, were synthesized in a supercritical carbon dioxide medium. The morphology of the synthesized copolymers was studied by scanning electron microscopy. Copolymers with IA, MME, and MEE were obtained in the form of regularly shaped particles of nearly 1 mu m in size without the addition of stabilizers.
