Synthesis and copolymerization of a new methacrylamide monomer included thiazole and cyclobutan ring

In this thesis, firstly 4-(l-methyl-l-mesityl-3-cyclobutyl)-2-N-l,3-thiazole-2-yl methacrylamide (MCTMA) monomer was prepared and characterized. The free radical copolymerization of this monomer with 2-[(5-methylisoxazol-3-yl)amino]-2-oxo-ethyl methacrylate (IAOEMA) was carried out in 1, 4-dioxane solvent by using AIBN initiator at 65 °C ±1 and were characterized by 1H NMR, 13C NMR and FTIR techniques. 1H-NMR analysis was used to determine the molar fractions of MCTMA and IAOEMA in the copolymers. The monomer-reactivity ratios were calculated according to the general copolymerization equation using Kelen-Tüdos (K-T) and Finemann-Ross (F-R) linearization methods. The thermal behaviours of copolymers with various compositions were investigated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
