Solution polymerization of acrylonitrile was investigated in N,N′‐dimethylformamide with various azo‐ and peroxo‐initiators. Investigations were carried out in a concentration range of initiatior from 0.0016 mol/l up to 0.0160 mol/l, constant acrylonitrile concentration of 3.8 mol/l and temperatures from 40°C up to 70°C. The computer combined dilatometric equipment for long time and high conversion investigations was used for estimation of the conversion‐time‐reaction. By means of obtained data a mathematical model was created. The model describes sufficiently precise acrylonitrile polymerization kinetics in N,N′‐dimethylformamide with various initiators in the used range of concentrations and temperatures.
