| titleOfInvention | Process for controlling pitch deposition from pulp in papermaking systems |
| abstract | ABSTRACT The invention relates to a process for controlling pitch deposition from pulp in papermaking systems which comprises adding to the pulp an effective amount of a polymer having hydroxyl groups pendant to the backbone of the polymer. The polymer can be polyvinyl alcohol having 50% to 100% hydrolysis. The polymer can also be a water-soluble copolymer having recurring units of nonionic hydrophilic monomers, anionic hydrophilic monomers and/or hydrophobic monomers, wherein the copolymer has at least 20 mol percent of vinyl alcohol. In another aspect, this invention comprises adding to the pulp an effective amount of a water-soluble polymer derived by substituting hydroxyl groups onto a preformed reactive polymer, wherein the water-soluble polymer has at least 20 mol percent of hydroxyl groups. |
