Influence of Termination and Transfer on Molecular Weight Distribution of Polymers. III. Spontaneous Termination

Abstract

Abstract This article deals with the kinetics of ionic polymerization with instantaneous initiation and spontaneous termination. The set of kinetic differential equations was solved rigorously by means of nonsteady-state analysis. Even though the expressions of the molecular size distribution function and other molecular parameters include an exponential integral function, all the molecular parameters can easily be computed numerically. Thus, this work is significant for controlling and regulating the relevant polymerizations.
