Abstract

Structural and rheological properties of polycomplex gels of sodium carboxymethyl cellulose (Na-CMC) with urea-formaldehyde oligomers were studied at various component ratios at 298–343 K. The polycomplexes were examined by IR spectroscopy. Mechanical characteristics of solutions of Na-CMC and its complexes with urea-formaldehyde oligomers and the size of structural units of these solutions were determined.
