A method of enhancing the dewatering of a paper sheet on a paper machine comprising adding to the paper sheet about 0.05 lb/ton to about 15 lb/ton, based on dry fiber, of one or more aldehyde functionalized polymers comprising amino or amido groups wherein at least about 15 mole percent of the amino or amido groups are functionalized by reacting with one or more aldehydes and wherein the aldehyde functionalized polymers have a molecular weight of at least about 100,000.

L'invention concerne un procédé destiné à améliorer l'égouttage d'une feuille de papier dans une machine à papier, consistant à ajouter à la feuille de papier environ 0,05 lb/tonne à environ 15 lb/tonne, en fibres sèches, d'un ou de plusieurs polymères fonctionnalisés par des aldéhydes comprenant des groupes amino ou amido, au moins 15 % molaire environ des groupes amino ou amido étant fonctionnalisés par mise en réaction avec un ou plusieurs aldéhydes, et les polymères fonctionnalisés par des aldéhydes ayant un poids moléculaire d'au moins environ 100 000.
