Synthesis, characterization and copolymerization new methacrylate and styrene of derivatives with side chain naphtalene ring

In this thesis, firstly 6-bromo-2-naphthyl-4-vinyl benzyl ether (NST) and 6-bromo-2-naphthyl methacrylate (NMA) monomers were prepared and characterized. The free radical copolymerization of this monomer 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 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 thermogravimetric analysis (TGA). The Tg values of the polymers were determined by differential scanning calorimetry (DSC).2012, X + 58 PagesKey Words: 6-bromo-2-naphthyl-4-vinyl benzyl ether (NST), 6-bromo-2-naphthyl methacrylate (NMA), , Monomer reactivity ratios, Thermal stability; Glass transition temperature.
