ABSTRACT
The problem “water in polymers” is one of the most actively and fruitfully developing problems of the physical chemistry of polymers. The polymer materials have come to a very extensive use as protective coatings, adhesives, insulating shells, packing materials, artificial leather, membranes, medicinal materials for different purposes, etc. At present, it is possible to state that in the late 1980s a fairly integral concept on the description of the translational mobility of the molecules of water dissolved in polymer has been formed in the practice of the investigation of diffusion in water-polymer systems. For partly crystalline polymers, the diagrams of state are characterized by a combination of the crystalline and amorphous equilibria. The regularities of the translational mobility of water in polymers and in any other systems as well, are assessed in terms of the absolute values of the coefficients of self- and interdiffusion, their concentration and temperature dependences, the specific features of sorption processes, permeability, and dissolution.
