Effect of amphiphilic copolymers of oligo(ethylene glycol)methacrylates on the synthesis of N-(dibutylaminomethyl)methacrylamide in an aqueous-organic emulsion

Abstract

The accelerating effect of adding a low molecular weight sulfonic acid surfactant (alkylbenzenesulfonic acid) and nonionic or containing sulfonic acid units amphiphilic copolymers of methoxy- and higher alkoxyoligo(ethylene glycol)methacrylates on the synthesis of a promising cationic monomer, N-(dibutylaminomethyl)methacrylamide, proceeding in an aqueous-amine emulsion, by the Mannich reaction, was revealed. The infl uence of the concentration of additives and the structure of copolymers on the catalytic effect is shown.
