Abstract: Production of water-sol?ble crosslinked auxiliari?s for the papermaking industry by reacting(a) one equivalent of NH groups of a polyalkylene polyamine having from 15 to 500 alkyleneimine units with(b) from 0.001 to 0.08 mole of a reaction product obtained from a polyalkylene oxide having from 8 to 100 alkylene oxide units with epichlorohydrin, in aqueous solution at a temperature of from 20.degree. to 100.degree.C. The viscosity of an aqueous solution containing 20% by weight of the crosslinked auxiliaries is from 300 to 1,500 centipoises (20.degree.C).

Abstract: PCT No. PCT/EP97/06857 Sec. 371 Date Jan. 27, 1999 Sec. 102(e) Date Jan. 27, 1999 PCT Filed Dec. 9, 1997 PCT Pub. No. WO98/29603 PCT Pub. Date Jul. 9, 1998Paper is produced by draining a paper stock containing process chemicals on a paper machine, a main stream of the paper stock and a dilution stream which consists of white water, contains at least 5% by weight of the process chemicals and amounts to 5-35% by volume of the total head box feed being fed via a head box to the paper machine wire. The papers thus produced have an excellent formation profile and an outstanding ash distribution.

Abstract: A process is disclosed for producing paper with a dry-strength and wet-strength finish by adding to the paper pulp combinations of hydrophilically modified polyisocyanates and polymers containing vinyl amine units, then by dewatering the paper pulp to form sheets of paper, or by treating the paper surface with hydrophilically modified polyisocyanates and polymers containing vinyl amine units. Also disclosed is the use of said combinations of polyisocyanates and polymers as dry-strengthening and wet-strengthening agents of hygienic and kraft papers.
