DRAINING AUXILIARIES IN THE PAPER ELABORATION. |
| abstract |
The present invention relates to aqueous compositions comprised of sulphonated aminotriazine / aldehyde polymers, for example, sulfated melamine / formaldehyde, processes for making these compositions, and methods for using these compositions as drain auxiliaries in papermaking. These compositions which become more turbid when diluted with water, provide improved drainage resolution compared to sulfonated arninotriazine / aldehyde polymers which do not become more turbid when diluted or compared with melamine / formaldehyde polymers which They are not sulphonated. |
