Abstract

A transparent hybrid photopolymer material is synthesized on the basis of (8-acryloyl-1,4-dithia-8-azaspiro[4.5]decan-2-yl)methyl acrylate and 3-[3-(3-mercaptopropyl)-1,1,3,5-tetramethoxy-5,5-diphenyltrisiloxane]propane-1-thiol. Using NMR spectroscopy and MALDI TOF mass spectrometry, the ability of the thiol-siloxane compound to undergo spontaneous hydrolytic condensation during storage is studied. The hybrid photopolymer films were obtained at different ratio of the components (from 16 : 1 to 1 : 2), and their thermomechanical and optical properties are investigated. The values of the storage modulus (0.9–2.3 GPa), the glass transition temperature (73–111°C), and the refractive index (1.56–1.59) are determined. On the basis of the 4 : 1 hybrid composition, a replica of relief microstructures with characteristic sizes of square elements of 5 × 0.8 μm is presented.
