摘要

Traditional and gradient interpenetrating polymer networks (IPN's) based on siliceous polyurethane and copolymer of butyl Methacrylate triethyleneglycol dimethacrylate by methods of volume dilatometry, vapour sorption and dielectric relaxation spectroscopy were investigated. The free energy of components mixture Δgx in the layers of gradient IPN's was calculated using the data of vapour sorption of solvent. It was shown that the free energy of components mixture, temperature transitions and molecular mobility in gradient IPN's are different and depend on the distance from the sample surface.
