Abstract

In order to perform future studies on the anticorrosive effect generated by the inclusion of benzotriazoles in anticorrosive mixtures, we performed the synthesis of a new polyacrylate containing benzotriazole as pendant groups. We have explored the reaction of 1,2,3-benzotriazole with ethanolamine and formaldehyde in a 2:1:2 ratio with the purpose of including an aliphatic spacer that reduces steric hindrance during polymerization. We have found that oxygen can also participate in the reaction as well as amine. We have synthesized the 2-(bis((1H-Benzo[d] [1,2,3] triazol-1-yl) Methylamino) Ethyl Acrylate (BMEA) monomer, which includes two pendant benzotriazole groups. After the synthesis of this monomer, we obtained the new material (PBMEA) by a solution polymerization. This material has a great trend to absorb moisture in contact with the air and we determine that this absorption seems stoichiometric.
