Abstract
Application of the gas-liquid chromatographic method to the analysis of the process of styrene-acrylonitrile radical copolymerization, especially with a monomer mixture rich in styrene, provided evidence for penultimate and antepenultimate effects. Methods are given for the determination of the corresponding reactivity ratios: r A ≈ 0, r AS = 0.55, r ASS = 0.50, r SSS = 0.25Keywords
