A stable, pourable, liquid composition contains a blend of at least 8% (usually at least 15%) water soluble high IV cationic polymer and a water soluble low IV cationic coagulant polymer which preferably comprises polyamine, and water soluble inorganic salt.
摘要:
Particulate water-soluble or water-swellable polymeric material is provided with a substantially uninterrupted continuous coating of crystalline material. Single particles or aggregates having a size below 1 mm in size can be made by mixing the polymeric particles with a substantially saturated or supersaturated aqueous solution of crystallizable material (optionally a melt of hydrate crystallizable material) and thereby depositing it as a continuous crystalline coating on the particles.

The invention relates to aqueous compositions, preferably aqueous compositions comprising at least one polymer with a particle size of more than 10 μm, formed from the polymerisation of a) at least one monomer of formula (I), wherein R1, signifies hydrogen or methyl, R2 signifies hydrogen or C1-C4alkyl, R3 signifies C1-C4alkylene, R4, R5 and R6 signify independently from each other hydrogen or C1-C4alkyl, X signifies —O— or —NH— and Y signifies Cl; Br; l; hydrogen-sulphate or methosulfate, b) and/or at least one non-ionic monomer, c) at least one cross-linking agent in an amount of 0-50 ppm by the weight of component a) and b) optionally at least one chain transfer agent with the proviso that (i) if the polymer is a cationic homopolymer then the amount of the crosslinking agent is always more than 0 ppm and less than 50 ppm.
摘要:
A process of flocculating and dewatering an aqueous suspension of suspended solids comprising, introducing into the suspension, (a) substantially linear polymer, (b) structured polymer, characterised in that the polymers are introduced into the substrate sequentially. The process brings about improvements in filtration.
摘要:
The present invention provides rheology modifiers, which are water-soluble polymers having a weight average molecular weight (Mw) of at least 1,000,000 g/mol and an intrinsic viscosity of at least 2.5 dl/g, both as determined by size exclusion chromatography, and wherein the water-soluble polymers are in the form of solid particles. It also provides mixtures of rheology modifiers comprising a first rheology modifier, which is a water-soluble polymer having a weight average molecular weight (Mw) of at least 1,000,000 g/mol and an intrinsic viscosity of at least 2.5 dl/g, both as determined by size exclusion chromatography, and a second rheology modifier, which has a weight average molecular weight of from 2,000 g/mol to 800,000 g/mol. It also provides coating composition containing the rheology modifiers, respectively, mixtures of rheology modifiers, a process for their preparation, a process for coating a substrate using these coating compositions and substrates coated with these coating compositions.
