Synthesis and Characterization of a New Methacrylate Polymer with Side Chain Benzofurane and Cyclobutane Ring: Thermal Properties and Antimicrobial Activity

Abstract

The synthesis of a new methacrylate monomer (Benzofuran-2-yl)(3-mesityl-3-methylcyclobutyl)- O-methacrylketoxime is described. The monomer was polymerized in 1,4 dioxane solution at 65 °C using azobisisobutyronitrile as an initiator. The monomer and its polymers were characterized by infrared, and 1H-NMR spectroscopy. The glass transition temperature of the polymer was investigated by differential scanning calorimetry and the apparent thermal decomposition activation energies ( Ed) were calculated by the Ozawa method using a Shimadzu thermogravimetric analysis thermobalance. The Ed were values were determined to be 231 kJ mol-1. The antibacterial and antifungal effects of the momomer and its homopolymer were also investigated on various bacteria and fungi.
