Copolymerization of N-[3-dialkylaminopropyl]methacrylamides with acrylic amides and esters in organic solvents

Abstract

The radical copolymerization of N-[3-(dialkylamino)-propyl]methacrylamides with a number of (meth)acrylic amides and esters in organic solvents over a wide range of molar ratios has been studied. Co-polymerisation constants for five polymerisation systems in 1,4-dioxane and toluene have been determined by the Feinman and Ross method. The influence of the solvent on the kinetics of the copolymerization of the studied monomers was found, which manifests itself in a change of the reactivity ratios of the monomers upon varying the polarity of the medium. For the obtained polymers, the presence of thermosensitive properties in aqueous solutions and the effect of the concentration and composition of copolymers on their solubility in water were shown.
