Abstract
The effect of postpolymerization (polymerization after current interruption) is observed and studied for electropolymerization composition based on acrylamide, N,N′-methylene bisacrylamide, formaldehyde, and zinc chloride. The possible causes of this phenomenon are considered. It is found that the main cause of postpolymerization is the catalytic effect of metallic zinc formed in the course of polymerization and initiation of further polymerization by metallic zinc after current interruption in an electrochemical cell. Kinetics and the mechanism of polymerization initiation by zinc are studied. It is shown that polymerization initiators may be other metals with the electrochemical potential in the studied solution sufficient for discharge of a zinc-acrylamide complex.
