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.

摘要： The present invention relates to a process of concentrating an aqueous suspension of solid particles comprising the steps of adding at least one organic polymeric flocculant to the suspension thereby forming flocculated solids in which the flocculated solids are allowed form a layer of solids and thereby forming a more concentrated suspension in which the process comprises the addition of an effective amount of an agent that is selected from the group consisting of free radical agents, oxidising agents, enzymes and radiation, in which the agent is applied to the suspension prior to or substantially simultaneously with adding the organic polymeric flocculant and/or the organic polymeric flocculant is added to the suspension in a vessel and the agent is applied to the suspension in the same vessel. The process is particularly suitable for solids liquid separation in which the flocculated solids are allowed to settle by sedimentation in a gravity thickener.

摘要： Water-immiscible liquids, for example oil-based drilling fluids, are thickened by the addition of an aqueous dispersion of polymeric particles that are water-insoluble, and insoluble but swellable polymer, in the water immiscible liquid. The particles have a unswollen average diameter of less than 10 .mu.m and at least 30% by weight are preferably in the range 0.5 to 5 .mu.m. Preferred polymers are formed from more than 80% by weight hydrophobic monomers, preferably alkyl (meth) acrylates, and up to 20% hydrophilic monomers, preferably unsaturated carboxylic acids, preferably acrylic acid.
