| titleOfInvention | METHOD FOR PAPER MANUFACTURE |
| abstract | 1. A method of making paper, including the use of a suspension of cellulose, including cellulose fibers and optionally fillers, dewatering the suspension of cellulose on a mesh or sieve to form a sheet and drying the sheet, in which the method includes a polymer additive, where the polymer additive is a polymer including an ethylenically unsaturated soluble in water or a potentially water-soluble monomer and an ethylenically unsaturated monomer containing a reactive group. 2. The method of claim 1, wherein the reactive group is selected from the group consisting of epoxy, isocyanate, and amidomethylol groups. The method of claim 1 or claim 2, wherein the polymer is prepared from a monomer mixture comprising at least one water-soluble or potentially water-soluble ethylenically unsaturated monomer; up to 10 mol%, preferably 5 mol% of an ethylenically unsaturated monomer containing a reactive group. 4. A process according to claim 1 or 2, wherein the polymer is obtained from a mixture of monomers comprising acrylamide and glycidyl methacrylate. The method according to claim 1 or 2, wherein the polymer has a weight average molecular weight of less than one million, preferably 50,000 to 300,000. The method of claim 1 or 2, wherein the polymeric additive is a dry strength additive. The method of claim 1 or 2, wherein the polymeric additive is a wet strength additive. The method according to claim 1 or 2, wherein the polymeric additive is a stock sizing reagent. The method according to claim 1 or 2, in which the polymeric additive is applied to the surface of the formed cellulose sheet, and in which |
