From the author: In the present study, a novel single hybrid monomer combining a vinylether and trimethoxysilane groups in the same molecule was synthesized by chemoselective hydrosilation and subjected to UV-irradiation in the presence of a triarylsulfonium salt. Through the UV-decomposition of this photoacid generator, two acid-catalyzed processes occurred simultaneously: the cationic polymerization of the vinyl ether functions and the sol-gel polycondensation of the alkoxysilyl groups, leading to a type II polyvinyl-polysilicate nanocomposite film. Both reaction kinetics were efficiently monitored by real-time Fourier transform infrared spectroscopy, and the influence of different key experimental parameters was investigated (laminated conditions, UV irradiation equipment, and film thickness). A particular attention was also given to the complete characterization of the hybrid microstructure by associating 29Si and 13C solid-state NMR. POLYM. ENG. SCI., 51:1466-1475, 2011.
