Title:
DRAINAGE AIDS IN PAPERMAKING
Document Type and Number:
WIPO Patent Application WO2001083885
Kind Code:
A3
Abstract:
This invention concerns aqueous compositions comprised of sulfonated aminotriazine/aldehyde polymers, e.g., sulfonated melamine/formaldehyde, processes for making these compositions, and methods of using these compositions as drainage aids in papermaking. These compositions, which become more turbid when diluted with water, provide improved drainage performance as compared to sulfonated aminotriazine/aldehyde polymers which do not become more turbid when diluted, or as compared to melamine/formaldehyde polymers which are not sulfonated.
