| Abstract: | Sodium and ammonium salt of allyl sulphonic acid have the same characteristics in radical copolymerizations with acrylonitrile in dimethyl formamide solution. In these cases, the copolymer composition equation does not adequately describe the copolymerization process; this is manifested in the fact that the reactivity ratios change with the initial monomer ratio. |
