Abstract: Cationic urea-formaldehyde condensates, which may be obtained by (a) the conversion of urea with alkanol amines in the mol ratio 1 to 6:1 at temperatures of 130 to 180 DEG C with separation of ammonia; (b) the methylolisation of the conversion products obtained in step (a) in an aqueous medium in the basic pH range with formaldehyde; (c) the condensation of the methylolisation products in an aqueous medium at a pH of 0 to 6, the condensation reaction being stopped by setting the pH to between 6.2 and 8 and, where necessary, diluting the reaction mixture with water; a process for manufacturing the condensates, and their use as stiffening agents in papermaking.

Abstract: Bipolar electrodes having two chambers for inflow and outflow of the reaction mixture to be electrolyzed. The chambers are separated from each other by a distance which is considerably larger than their width and the inlets and outlets are on the same side of the electrode. Electrodes of this kind are suitable, for example, for the Kolbe synthesis of dicarboxylic esters from dicarboxylic half-esters. Such esters are useful as plasticizers.

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.
