    摘要： A microcapsule comprising A) a core containing a hydrophobic liquid or wax, B) a polymeric shell comprising a) a polymer formed from a monomer mixture containing: i) 1 to 95% by weight of a hydrophobic mono functional ethylenically unsaturated monomer, ii) 5 to 99% by weight of a polyfunctional ethylenically unsaturated monomer, and iii) 0 to 60% by weight of other mono functional monomer, and b) a further hydrophobic polymer which is insoluble in the hydrophobic liquid or wax. The invention includes a process for the manufacture of particles and the use of particles in articles, such as fabrics, and coating compositions, especially for textiles.

    摘要： A microcapsule comprising a core containing a hydrophobic liquid or wax within a polymeric shell, in which solid particles insoluble in the hydrophobic liquid or wax are distributed throughout the core, wherein an oil soluble dispersant polymer is adhered to the surface of the solid insoluble particles. Processes of obtaining the microcapsules and dispersions of microcapsules in a liquid are claimed. The microcapsules can be used in a variety of applications particularly in the field of thermal energy storage. Suitably the microcapsules can be designed to have a particular density and can be used in the transfer fluids where the density of the microcapsules are the same as the carrier fluid.

    摘要： A particulate composition comprising particles which consist of a shell wall surrounding a hydrophilic core, wherein the shell wall is formed from a polymeric coacervate and wherein the particles comprise a polymeric amphipathic stabiliser. Also claimed is a process of producing a particulate composition comprising particles which consist of a shell wall surrounding a hydrophilic core, comprising the steps of a) forming an aqueous liquid that contains a wall building material that is capable of forming the shell wall by coacervation, b) dispersing the aqueous liquid into a water immiscible liquid, which comprises a stabilising substance to form a dispersion that comprises aqueous droplets dispersed in a continuous phase of water immiscible liquid, c) subjecting the dispersion to coacervation conditions, such that the wall building material coacervates at the surface of the aqueous doplets, characterised in that the stabilising substance comprises a polymeric amphipathic stabiliser. Preferably the particulate composition obtainable by the process contains an active ingredient and is used in a detergent composition. The active ingredient preferably comprises any of detergency building ingredients, a buffering system and/or a sequesterant and/or detergent builder. Citric acid is a particularly preferred active ingredient.
