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. Characterization was achieved by FT-IR, 13 C NMR, 1 H NMR, and 11 B 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 polymerization. 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. Copolymerization 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 methods. 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.
The overmolding of short fiber reinforced polymer compounds onto continuous fiber reinforced composite substrates provides design flexibility and the ability to tailor stiffness, strength, and damage tolerance for structural applications. In this work, a novel molding approach that enhances the bond-
