Polymerization of Acrylonitrile in Solution IV. The Retardation using Nitro-derivatives of Phenol
In order to confirm the mechnism of the termination reaction in a heterogeneous polymerization of acrylonitrile, three nitroderivatives of phenol; p-nitrophenol, 2, 4-dinitrophenol and picric acid are taken as retarder. The results are as follows; the mono-derivative has no effect, but the reaction...

| Summary: | In order to confirm the mechnism of the termination reaction in a heterogeneous polymerization of acrylonitrile, three nitroderivatives of phenol; p-nitrophenol, 2, 4-dinitrophenol and picric acid are taken as retarder. The results are as follows; the mono-derivative has no effect, but the reaction rate in the presence of the di-and tri-derivatives measured at 40 and 58°C respectively is proportional to represents the concentration of each nitroderivative, concentration of the monomer and benzoylperoxide being taken as constant. It is also known that the mean molecular weight of the polymer becomes smaller as the picric acid concentration increases. These results indicate that the present chain termination reaction must be of monomolecular. |
