Polyglycerol, polymerized glycerol, is a highly viscous and hygroscopic liquid. It is can be utilized cosmetics, food additive, and raw material for various derivatives. We developed a novel polyglycerol-based monomers which consist of polyglycerol skeleton, with or without polyethylene oxide chain, and reactive end groups such as epoxy, acrylate, methacrylate, and alkoxysilane. The polyglycerol backbone and its EO adduct act as soft segments in cross-linked network. After the examination of their flexibility, curing rate, and stress relaxation effect, we successfully applied these materials to flexible coating. Moreover, our research indicated that the hydrophilic nature of the polyglycerol-EO skeleton enables the moisture to be absorbed/released repeatedly. By applying this technology, we offer the wide potentials of polyglycerol-based soft materials including novel hydrogel and anti-fog coating.
