(EN) POLYMERIC COMPOSITIONS AND METHODS OF EMPLOYING THEM IN PAPERMAKING PROCESSES
(FR) COMPOSITIONS POLYMÈRES ET PROCÉDÉS LES UTILISANT DANS DES PROCÉDÉS DE FABRICATION DE PAPIER
Abstract
(EN) A polymer comprising i) a synthetic polymeric component that has been formed from an ethylenically unsaturated water-soluble or potentially water-soluble monomer and an ethylenically unsaturated monomer carrying a reactive group, wherein the reactive group is directly reactive with a cellulose binding domain protein; and ii) a protein component consisting of a cellulose binding domain protein, wherein the cellulose binding domain protein. The polymer is particularly suitable as a dry strength resin in a paper making process. It can also be used as a wet strength resin, internal sizing agent or surface sizing agent.
(FR) La présente invention concerne un polymère qui comprend i) un composant polymère synthétique formé à partir d’un monomère non saturé éthyléniquement soluble dans l’eau ou potentiellement soluble dans l’eau et d’un monomère non saturé éthyléniquement qui porte un groupe réactif ; ledit groupe réactif réagit directement avec une protéine à domaine de liaison à la cellulose ; et ii) un composant protéique constitué d’une protéine à domaine de liaison à la cellulose. Le polymère est particulièrement approprié comme résine conférant de la résistance à l'état sec dans un procédé de fabrication de papier. Il peut également être utilisé comme résine conférant de la résistance à l'état humide, agent de collage interne ou agent de collage de surface.
