Preparation of a fiber-forming tercopolymer of acrylonitrile, methyl acrylate and 2-acrylamide-2-methylpropanesulfonic acid in dimethylformamide and dimethyl sulfoxide
In order to choose ways to optimize the technological process of obtaining a fiber-forming tercopolymer (FTP) based on acrylonitrile, methyl acrylate and 2-acrylamide-2-methylpropanesulfonic acids, under conditions of varying the content of the initiator in the reaction mixture, a comparative analysis of homophase free radical synthesis of FTP at a temperature of 75 °C in technologically acceptable aprotic solvents (dimethylformamide and dimethyl sulfoxide) was carried out. The influence of the solvent nature on the dynamics of the synthesis of FTP is shown. The macrokinetic parameters of the considered processes necessary for practical implementation are determined.
