Investigation of Morphology and Sorption-Diffusion Characteristics of Segmented Polyetherurethanes
Source abstract
Abstract
Abstract Sorption and diffusion of water into a number of segmented polyetherurethanes were studied. It has been demonstrated that the heat of sorption in the temperature range of 25°–55° equals approximately zero. The activation energy of the diffusion process is approximately 10 kcal/mole. The influences of synthesis and film formation conditions, ratios of flexible/rigid blocks, nature of the flexible block and heat-treatment on the degree of microphase separation were studied. The control of supermolecular structure of samples was performed using X-ray diffraction method. DSC. IR-spectroscopy and isotropic H → D exchange.
