Photopolymerization of Ricinodendron heudelotii oil and methyl methacrylate in presence and absence of iron(ΙII) oxalato complex as photoinitiator

In the first step of this study, 2‐[(methoxy‐1,3‐benzothiazole‐2‐yl)amino]‐2‐oxoethyl methacrylate (MBAOM) monomer was synthesized and characterized. Then, a series copolymers were obtained by free‐radical copolymerization method of MBAOM and glycidyl methacrylate, which is a commercial monomer at 65°C in 1,4‐dioxane solvent. Structural characterizations of synthesized monomer and copolymers were carried out using Fourier transform infrared spectrophotometer and nuclear magnetic resonance spectroscopy (1H and 13C‐NMR) instruments. The composition of the copolymers was estimated by elemental analysis. The thermal behaviors of all the polymers have been investigated using the differential scanning calorimetry and the thermogravimetric analysis. A kinetic study of the thermal decomposition of copolymers was investigated using thermogravimetric analyzer with non‐isothermal methods selected for analyzing solid‐state kinetics data. The activation energy (Ea) values were calculated via Kissinger and Ozawa models in a period of α = 0.10–0.80. Photostability of the copolymers was investigated. Also, the biological activity of the copolymers against different bacterial and fungal species has been investigated.
