Abstract
The rheokinetics of gelation of poly(vinyl alcohol) aqueous solution systems with chemical crosslinks and physical junctions, including hybrid ones, has been studied. Hydrogels are obtained using glutaraldehyde and/or tetramethoxysilane as crosslinking components. It has been shown that at the initial step of gelation (until the systems reach critical gelation conversion) the efficiency of the process is determined by the concentration of the crosslinking agent rather than the chemical nature of network crosslinks. A comparative analysis of the mechanical properties of chemical, physical, and hybrid hydrogels at various temperatures is performed. Quasi-static uniaxial compression and tension tests make it possible to establish the contribution of network junctions and crosslinks to the behavior of hybrid hydrogels and their distinctive features.
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.
