    摘要： The present invention teaches a cationically charged or neutral microcapsule particle comprising an oil soluble or dispersible core material and a wall material at least partially surrounding the core material, the microcapsule wall material comprising the reaction product of a first composition in the presence of a second composition comprising an emulsifier which is cationic or nonionic, the first composition comprising a reaction product of i) an oil soluble or dispersible amine with ii) a multifunctional acrylate or methacrylate monomer or oligomer, an oil soluble acid and an initiator. The cationic or nonionic emulsifier comprises a water soluble or water dispersible material and optionally a water phase initiator. The first composition initiator and the water phase initiator is an energy-activated initiator. The reaction product of the first composition and second composition results in the formation of a population of microcapsules having a microcapsule wall of low permeance to the core material and having a zeta potential of −5 millivolts or greater. The resulting microcapsules have adherence to anionic surfaces.

    摘要： A process of forming microcapsules is described. The microcapsule population is formed by providing an anionic or cationic, solid hydrophilic core material; providing an oil continuous phase, the oil continuous phase comprising one or more esters with chain length up to about 18 carbons. Emulsification is achieved by subjecting the mixture to high shear agitation and heating the mixture for a time sufficient to enable acid or amine acrylate or methacrylate and multifunctional acrylate or methacrylate to form a prepolymer which migrates to the anionic or cationic solid hydrophilic material, thereby forming prepolymers adhered to the hydrophilic core materials. Temperature is held or heating continued for a time sufficient to enable the prepolymer to flow onto and coalesce into a continuous film surface coating on the hydrophilic core material. Heating is carried out or light exposure or both for a time and temperature sufficient to cross link the prepolymers.

    摘要： The invention discloses a population of selected permeability microcapsule particles comprising an oil soluble or dispersible core material and a wall material at least partially surrounding the core material. The microcapsule wall material comprises the reaction product of a first composition in the presence of a second composition comprising an anionic emulsifier. The first composition comprises a reaction product of i) an oil soluble or dispersible amine with ii) a multifunctional acrylate or methacrylate monomer or oligomer, an oil soluble acid and an initiator. The anionic emulsifier comprises a water soluble or water dispersible acrylic acid alkyl acid copolymer, an optional initiator and an alkali or alkali salt. The reaction product of the first composition and second composition can result in the formation of a low permeability microcapsule wall. Optionally, one or both of the first composition initiator or water phase initiator is an energy-activated initiator, such as a UV initiator. The reaction can proceed by exposing the respective compositions to actinic radiation. Microcapsules of selected permeability can be produced by the process of the invention.

    摘要： A novel method of forming oil in water process is disclosed. According to the invention process are obtained by steps comprising dispersing an oil soluble amine modified polyfunctional polyvinyl monomer and an oil soluble bi- or polyfunctional vinyl monomer along with a thermal or UV free radical initiator (optionally included in one or both of the oil or water phases) and an organic acid into an internal phase oil; heating or UV exposing for a time (and temperature) sufficient to oligomerize the amine modified polyfunctional polyvinyl monomer and oil soluble bi- or polyfunctional vinyl monomer forming a pre-polymer. Thereafter the process involves adding to the oil phase oil a water phase comprising a dispersion in water of an anionic emulsifier (and optionally initiator), and adding an emulsifying agent. Emulsification of the oil phase into the water phase (O/W) is controlled through the quantity of water employed. The emulsion is then UV exposed or heated for a time (and temperature) sufficient to decompose the free radical initiators in the oil and/or water phases; thereby forming microcapsule wall material at the interface of the water and oil phases.
