TL;DR: A strong concentration effect was found in a course of copolymerization of higher N-alkylacrylamides with higher alkyl acrylates in toluene, where the fraction of amide functions in copolymers obtained at low degrees of conversion decreases significantly with an increase in total concentration of monomers in solution.

Abstract: A strong concentration effect was found in a course of copolymerization of higher N-alkylacrylamides with higher alkyl acrylates in toluene, where the fraction of amide functions in copolymers obtained at low degrees of conversion decreases significantly with an increase in total concentration of monomers in solution. It was established that the observed effect is independent of the structure of alkyl substitutes for both types of monomers. The data gathered with the aid of IR spectroscopy and computer modeling show that this concentration effect relates to the formation of amide associates in solution. The concentration effect was absent for the copolymerization of higher alkyl methacrylates and higher alkyl acrylates.
