Abstract
Method for controlling the deposition of organic contaminants from the pulp and papermaking systems using water soluble aminoplast ether copolymers is described herein. The aminoplast ether copolymer can be used alone or in combination with one or more additives. The pulps to be treated include mechanical, chemical, semi-chemical pulps; sulfide pulp; recycled old newspapers; mixed office wastes; corrugated boxes; and their combinations. The use of water soluble aminoplast ether copolymers to control or prevent pitch and stickies deposition improves down stream performance of papermaking equipment increasing mill efficiency and improving paper quality.
