Rheology of crosslinking poly vinyl alcohol systems during film formation and gelation

摘要: Gelation of crosslinking polymers, with ionic groups, is interest in membrane processing these materials. The gelation polyvinyl alcohol the presence an crosslinker, sulfosuccinic acid, was monitored through rheological measurements. evolution material functions during film formation, which involves solvent evaporation and crosslinking, observed at different polymer crosslinker concentrations. Relative effect water leading to physical chemical examined. To understand type, rheology nonionic glutaraldehyde also gel points as well network parameters for covalent networking systems were depended on type polymer/crosslinker However, qualitative behavior formation largely similar, demonstrating dominating evaporation. Crosslinking absence examined temperatures. It can be concluded that similar mechanism involved, independent temperature, temperature range interest. concentration properties near insignificant though marginally significant crosslinker.
