Abstract

Novel hybrid oligomers based on a UV-curable bisphenol-S epoxy dimethacrylate (DBSMA) were synthetized. DBSMA was modified with various amount of (3-isocyanatopropyl)triethoxysilane coupling agent. The modification degree of the hybrid oligomer was varied from 0 to70 wt %. The photopolymerization kinetics was monitored by a real-time infrared spectroscopy. The conversion and rate of hybrid coatings increased with the increase in modification degree. UV-curable, hard, and transparent organic–inorganic hybrid coatings were prepared. They were performed by the analyses of various properties such as surface and mechanical properties. Results from the mechanical measurements showed that the properties of hybrid coatings improved with the increase in modification degree. The thermal behavior of coatings was also investigated. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
