Synthesis and Characterization of an Acrylamide-Based Resin for Coating Application

Abstract

To synthesize an acrylamide-based resin, two functional acrylamide monomers, N-methylolacrylamide and N-butoxymethylolacrylamide, were prepared and copolymerized separately with two methacrylate esters: methylmethacrylate and butylmethacrylate. The resin derived from N-methylolacrylamide proved to be inadequate due to its instability. To adjust the necessary amount of the reagents needed for the synthesis, different concentrations of the initiator, benzoyl peroxide, and various concentrations of the molecular weight regulator, tertio-dodecyl mercaptan transfer agent, were tested by monitoring the resulting viscosity and conversion. The paint formulation containing N-butoxymethylolacrylamide co-monomer was characterized in terms of hardness, impact and embossing resistance, gloss and adhesion to a metal substrate. The performance properties, which were compared with those of a commercial paint composition, considered as a reference, were overall satisfactory.
