ABSTRACT The specific dependencies of the initial reduced polymerization rate on the initial monomer concentration were introduced for the radical homopolymerization of N‐[3‐(dimethylamino)propyl]acrylamide (DMAPA) and N‐[3‐(dimethylamino)propyl]methacrylamide (DMAPMA) in toluene, DMF, and water at 60 °С. The degree of the monomer self‐association and the ratio of the amides constituting various types of associates were evaluated using FT‐IR spectroscopy and computer simulation for the solutions of DMAPA and DMAPMA in toluene with different monomer concentrations. The hypothesis linking the type of predominant pre‐reaction monomer assemblies and the revealed concentration effects was proposed for the homopolymerization of aminoamide monomers and explaining unconventional experimental data. © 2016 Wiley Periodicals, Inc.
