Abstract: 
An approach to water emulsions modification with structure forming additives, namely cellulose esters, is proposed in the article. Influence of the film former origin on the system rheological properties at different shear-strain rates was examined. Structural and mechanical, as well as rheological properties of the studied systems were determined. The results confirm that hydroxyethylcellulose has a greater structure forming effect in comparison with carboxymethylcellulose. Hydroxyethylcellulose provides well-definite pseudoplastic properties to the two-component systems that facilitate the production and application of paints. The results of the investigation could be used in the emulsion paint (coatings) production.
