Points from Foregoing Letters

    Abstract

    Prof. A. C. Cuthbertson, Geoffrey Gee and Prof. E. K. Rideal find that pure vinyl acetate does not polymerize measurably at 100° C. even in the presence of oxygen. A peroxide derived from acetaldehyde, however, catalyses the reaction. The authors suggest that the discrepancy in the findings of various observers between the rate of polymerization of gaseous and liquid styrene may be likewise explained by the presence of a peroxide catalyst in the liquid phase.
