AQUEOUS DISPERSION OF HIGH INTRINSIC VISCOSITY POLYMER AND ITS PRODUCTION AND USE |
| 摘要 |
<p>A stable, pourable, liquid composition contains 20 to 60% by weight of a blend of a water soluble high IV polymer and a water soluble low IV cationic coagulant polymer, is selected from polyamines, cationic dicyandiamide polymers and polymers of 70 to 100% ethylenically unsaturated cationic monomer with 0 to 30% by weight acrylamide, and contains 0.01 to 1 part by weight of a water soluble multi-hydroxy compound per part by weight of the coagulant polymer.</p> |
