title: UREA FORMALDEHYDE OLIGOMERS – INHIBITORS OF POLYSACCHARIDE DESTRUCTION OF SODIUM CARBOXYMETHYL CELLULOSE, PRODUCED FROM WOOD PULP
abstract: The objective of this work is to study the kinetics of changes in the structure and properties of interpolymer complexes obtained on the basis of sodium carboxymethylcellulose polysaccharide (Na-CMC) with urea-formaldehyde oligomers (UFO). The stability period of solutions of Na-CMC interpolymer complexes with UFO determination of viscosity at various temperatures has been studied. Experimental data show that when storing aqueous solutions of Na-CMC, the viscosity decreases due to changes in the
