摘要： A cross linked high molecular weight polymer formed from a water soluble monomer or blend of monomers and which has IV and/or solubility and/or rheology properties indicating that it would be unsuitable for use as a flocculant can be used as a flocculant after shearing the polymeric material. The shearing may be applied to the polymeric material before addition to the suspension that is to be flocculated or can be applied to the suspension that is being flocculated. The shearing increases the intrinsic viscosity of the polymeric material and can improve its rheology and solubility. The polymeric material must be of high molecular weight.

摘要： The flocculation performance, for instance on low pressure or other pressure filtration (such as a belt press), of a solution of a high molecular weight organic polymeric flocculant having IV above 4 is improved by subjecting the solution to degradation, preferably by mechanical shear such as through a Silverson mixer or by a fast rotating blade.
