Abstract

<p>Polyglycerol, polymerized glycerol, is a highly viscous and hygroscopic liquid. It can be utilized as cosmetics, food additive, and raw material for various derivatives. We developed 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.Due to their flexibility, high curing rate, and stress relaxation effect, we successfully applied these materials to the flexible coating. Moreover, our research results indicated that the hydrophilic nature of the polyglycerol-EO structure enables the moisture to be absorbed/released repeatedly. By applying these properties, we offer the wide potentials of polyglycerol-based soft materials including novel hydrogel and anti-fogging coating.</p>
