New ultraviolet (UV) curable prepolymer, 2–hydroxy–3–[p–(1–{2–hydroxy–3–(isopro– phenylcarbonyloxypropoxy) phenyl} methylcyclohexyl) phenoxy] propyl acrylate (BISCHDA) was synthesized by the reaction of p–[1–(p–hydroxyphenyl) methylcyclohexyl] phenol with methylcyclohexanone, epoxidation with epichlorohydrin followed by addition reaction with acrylic acid. All synthesized compounds were characterized by 1H-NMR, 13C-NMR and FT-IR spectroscopy. Several UV-curable formulated solutions were prepared…
