CA 2524205

The present invention relates to a method for controlling pitch and stickies deposit in a pulp and papermaking process using crosslinked cationic polymers made by controlled addition of a water soluble radical initiator at reaction temperature with agitation for chain extension and crosslinking.

La présente invention a trait à un procédé de contrôle de dépôt de poix et de matières gluantes dans un traitement de pâte et de fabrication de papier mettant en oeuvre des polymères cationiques réticulés produits par l'ajout contrôlé d'un initiateur radicalaire hydrosoluble à une température de réaction sous agitation en vue de l'allongement de chaîne et de réticulation.
