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 agglomarting in papermaking processes.
