Graphical Evaluation of the Rate Constants of the Elementary Reactions in the Acrolein Polymerization with the Potassium Persulfate-Silver Nitrate Redox System

Abstract

Abstract A quantitative study was made of the redox-polymerization of acrolein initiated by the potassium persulfate-silver nitrate system. The reaction mechanism of this polymerization was proposed on the basis of the results of the time-conversion, time-molecular weight curves, and also on the basis of the characteristic features of this polymerization, reported in a previous paper. The rate constants of the elementary reactions in this polymerization were estimated by a graphical method. In the early stage, neither the termination nor the transfer reaction is very remarkable as the initiation reaction, but in the later stage the termination reaction by a recombination of the polymer radical and the transfer reaction increase with the reaction time, as does the initiation reaction also.
