Abstract:
An unsheared, water-soluble, branched, nonionic, polymeric flocculant comprising at least one ethylenically unsaturated non-ionic monomer, said polymeric flocculant having a branching agent content of from about 4 to about 80 molar parts per million based on initial monomer content, and a solution viscosity of at least about 1.9 mpa.multidot.s measured in a Brookfield viscometer with a UL adapter at 25.degree. C. on a 0.1 percent, by weight, polymer solution in 1M NaCl at 60 rpm, said flocculant being efficient when added as a true solution to dispersions of suspended solids for the purpose of releasing water therefrom.
