Abstract

Type II polyether–silica hybrid films were successfully synthesized from 3-(glycidyloxypropyl)trimethoxysilane (GPTMS) through a novel photobase-catalyzed sol–gel and anionic polymerization using an α-amino acetophenone derivative as a tertiary amine photogenerator. We report here some characterization evidence establishing that the hybrid precursor undergoes two different polymerization reactions in a single step. FTIR analysis as well as solid-state NMR (13C, 29Si) shed light onto the tandem formation of the silica network and the polyether chains. The prominent role played by α-amino acetophenone in the dual catalysis was also highlighted by comparison with other O-acyloxime-based photobase generators.
