N2 - Boron methacrylate (BAc) monomer was synthesized via an esterification reaction. Boric acid, neopentyl glycol, and 2-hydroxyethyl methacrylate (HEMA) were reacted to obtain boron-containing acrylic monomer. Character-ization was achieved by FT-IR, 13C NMR, 1H NMR, and 11B NMR and the results for the synthesized monomer were compared to those for HEMA. Homopolymer and copolymers with styrene (St) were synthesized via free radical poly-merization. The properties of the synthesized styrene copolymers were investigated using several techniques. Monomer reactivity ratios for the studied monomer pair were calculated using the extended Kelen{Tüdos method. Copolymeriza-tion compositions and reactive ratios showed that the obtained copolymers had random characters. Thermal behaviors of the synthesized polymers were studied by thermal gravimetric analysis and differential scanning calorimetry meth-ods. Boron methacrylate homopolymer showed one glass transition temperature at 73.7°C. Depending on copolymer composition, the glass transition temperatures of boron methacrylate-styrene copolymers were between 68.4°C and 81.5°C.
