Abstract: The method of optical polarimetry has been used to study the hydrophilicity of polyurethane. It has been shown that swelling of the elastomers increases the initial optical anisotropy and decreases the photoelasticity coefficient. The change in optical anisotropy at deformation of polyurethane under conditions of a long-term action of constant force has been investigated. The nuclear magnetic resonance relaxometry method with an integral transformation inversion has been used to study the effect of polyurethane swelling on the dynamics of elastomer macromolecules.

Keywords: hydrophilicity, polyurethane, polarimetry, relaxometry, nuclear magnetic resonance.
