摘要

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.
