Аннотация

This study investigates the influence of the molecular architecture of sulfonated cellulose (linear and branched structures) on its adsorption behavior and rheological properties in montmorillonite dispersions. A series of polymers with similar degrees of sulfonation but different macromolecular architectures were obtained through controlled synthesis. Molecular characteristics of the polymers were determined using gel permeation chromatography coupled with multi-angle light scattering, allowing evaluation of branching parameters. Adsorption studies revealed that linear polymers form denser adsorption layers on the montmorillonite surface, while branched polymers produce thicker adsorption layers with greater effective thickness. Rheological analysis demonstrated significant differences in the mechanism of action: linear sulfonated cellulose acts as an effective deflocculant, reducing the viscosity of the suspension, whereas branched structures induce the formation of an elastic three-dimensional network and significantly increase the storage modulus of the system. The results confirm that macromolecular architecture is a key factor enabling targeted control of the rheological behavior of dispersed systems.
