Abstract
The effect of thermal prehistory and mechanical field on the morphology and physicomechanical and thermal properties of poly(vinyl alcohol) cryogels has been studied. Using the methods of rheometry, DSC, and X-day diffraction analysis it is revealed that an increase in the heat treatment temperature of cryogels causes a rise of the melting temperature and a change in the crystallinity of PVA cryogels, as is typical for the annealing phenomenon. It is established that the annealing of PVA cryogels formed under repeated freezing with simultaneous forced compression contributes to the formation of cryogels with the spatial network being stable up to the onset of solvent boiling.
期刊介绍:
Polymer Science, Series A is a journal published in collaboration with the Russian Academy of Sciences. Series A includes experimental and theoretical papers and reviews devoted to physicochemical studies of the structure and properties of polymers (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed. Online submission via Internet to the Series A, B, and C is available at http://polymsci.ru.
