The article is devoted to studying of influence of nitrogen-containing pitches on properties of technical types of paper. Influence of conditions of receiving pitches on hydrophobic and physical mechanical properties of samples of paper from cellulose and waste paper is shown. It is established that efficiency of effect of studied pitches significantly depends on a look fibrous the semi-finished products, used in paper composition. Increase of efficiency of strengthening effect of studied nitrogen-containing pitches at reduction of a molar ratio carbamide : formaldehyde to 1.0 : 5.9 is shown.
