Abstract: O.Z. 0050/40658 Cationic urea-formaldehyde condensates useful as strength enhancers in papermaking are obtainable by (a) reacting urea with at least one alkanolamine in a molar ratio of from 1:1 to 6:1 at from 130 to 180.degree.C with elimination of ammonia, (b) methylolating the reaction product of stage (a) with formaldehyde in an aqueous medium at a basic pH, (c) condensing the methylolation product in an aqueous medium at pH 0-6 and terminating the condensation reaction by adjusting the pH to 6.2-8 and optionally diluting the reaction mixture with water.

Abstract: Condensates containing urea and formaldehyde in a molar ratio of from 1:2.5 to 1:4.5 are converted into wood glue by allowing the viscosity to increase at a pH of from 1 to 3 and at only slightly elevated temperature and then adding urea at a pH of 7 to 9.
