Abstract:
1. A composition comprising, as a dispersion: an aqueous phase containing a dissolved water soluble cationic coagulant polymer and if needed a dissolved inorganic salt, and a dispersed water soluble flocculant polymer, wherein, the water soluble flocculant polymer is formed of a water soluble ethylenically unsaturated monomer or monomer blend which are polymerized in the aqueous phase, the water soluble cationic coagulant polymer is cationic poly(alkyleneamine), which is the reaction product of the following reaction (I) wherein R is selected from the group consisting of alkyl radicals containing from 1 to 4 carbon atoms m is an integer of from 1 to 4, the amount of dissolved inorganic salt is less that 10% by weight of the composition, the composition is in a stable, pourable, dispersion form, and the composition contains 10 to 60% by weight of a blend of the water soluble flocculant polymer and the water soluble cationic coagulant polymer.
