AQUEOUS DISPERSIONS OF WATER-SOLUBLE POLYMERS WITH COMBLIKE STABILIZERS |
摘要 |
The invention relates to aqueous dispersions of water-soluble polymers of N-vinyl-carboxamides, which are substantially salt-free and comprise anionic polymeric stabilizers having a comb-like molecular structure, processes for the preparation of the dispersions in the presence of anionic polymeric stabilizers having a comb-like molecular structure and the use of the dispersions as retention aids or fixing agents in papermaking. |
