Abstract
The invention is directed to methods and compositions for reducing the deposition of pitches and stickies in a papermaking process. The method involves introducing an anionic glycerol-based polymer to the papermaking process. This anionic polymer prevents the pitches and stickies from depositing and agglomerating in papermaking processes.
Claims16
A method of reducing the deposition of organic contaminants in papermaking processes, comprising adding to pulp or a papermaking system an effective amount of a composition comprising an anionic lipophilic branched, cyclic glycerol-based polymer, wherein the composition selectively bonds with the organic contaminants to form a complex and the complex is stable in papermaking processes.
