Abstract
The swelling kinetics of polymer gels has been studied in water and aqueous solutions by optical micrometry. Cross-linked hydrophilic polymers based on polystyrene and poly(vinyl alcohol) have been used as gel-forming materials. The effects of the natures of the matrices and polar groups of the polymers and their cross-linking densities and granule sizes, as well as the properties of external phase, on the swelling kinetics of the polymer gels have been investigated. The experimental results have been processed in terms of a heterophase kinetic model. The applicability of the model to describing the behavior of all studied systems has been shown.
