摘要： The present disclosure relates to fragrance materials encapsulated within polymeric materials in the form of microcapsules of polymer encapsulated fragrance. The microcapsules are mixed with a water-based binding agent so that a coating forms on the microcapsule in situ, after which the coated microcapsules may be applied to hard surfaces of a product, from which controlled release of the fragrance is provided over time as the product is subjected to normal handling by a user.

摘要： A method of mercury-free photochemical micro-/nano-encapsulation of an active material is a process for obtaining Micro-/nano-capsules by means of curing by UV LED radiation at ambient or even cold temperatures. A stirrer photo-reactor made from glass or transparent plastics can be used but mixed flow reactor could be also employed. Appropriate mixing is sufficient to expose all droplets, which contain an active material surrounded by curable-shell materials in the emulsion to the LED radiation. Using the optimum light intensities and reactions' times is critical for encapsulating the active material with a high efficiency and producing a high quality micro-/nano-capsules, Solar monochromator device can also be used as long as it generate the same radiation with a narrow/single wavelengths as the LED device. Light emitted diode (LED) is a mercury-free UV radiation source with a long operating life time and an instant ON-Off, it has a high efficiency, a very low cooling requirements and cost-efficient in photochemical encapsulation. It reduces the time of microencapsulation from 6 hours to a less than 5 minutes. It has a significant decrease in manufacturing cost, waste-water, unconverted monomers, and leftover active phase change material (PCM) compared to other methods. Conversion of more than 90% of monomers can be achieved, and encapsulation efficiency can reach 100% at optimum conditions. This is in addition to the ability of this invented technology for encapsulate volatile and heat sensitive active materials at ambient as well as low temperatures. Normal glass or transparent plastics can be used as a reactor material. Only the matched useful wavelength radiation is emitted by LED without having other wavelengths which might have a bad impact on the encapsulation process.

摘要： Delivery particles encapsulating oily core materials have a shell material of hybrid poly acrylate and poly(beta-amino esters) (PAC/PBAE). The delivery particles may have a single shell of hybrid PAC/PBAE, dual shells including hybrid PAC/PBAE in an inner shell and PBAE in an outer shell crosslinked to the inner shell, or multiple shells including PAC in an inner shell, hybrid PAC/PBAE in a transitioning shell, and PBAE in an outer shell. Formation of the delivery particles includes polymerization between multifunctional amine and multifunctional acrylate to produce a water soluble PBAE; polymerization between the preformed PBAE prepolymer having free methacrylate moieties reactive with a multifunctional (meth)acrylate in the oil phase, or at an interface of the water and oil phases to produce PAC wall, polymerization between polyacrylate and the amine moiety of PBAE prepolymer to produce hybrid PAC/PBAE delivery particle wall; and polymerization between multifunctional acrylate and primary or secondary amine moiety of the PBAE prepolymer to form a PBAE outer shell.

摘要： The wet adhesion of a coating composition may be improved through the use of voided latex particles as opacifying agents which contain a hollow interior as well as an outer shell of a polymer containing functional groups such as amino, 1,3-diketo, urea or ureido. Other types of functional groups may be introduced to the outer shell polymer in order to vary other desired characteristics of the coating. The voided latex particles are non-film-forming.

摘要： Microcapsules encapsulating oily core materials have a shell material of hybrid polyurea and poly(beta-amino esters) (PU/PBAE). The microcapsules may have a single shell of hybrid PU/PBAE, dual shells including hybrid PU/PBAE in an inner shell and PBAE in an outer shell crosslinked and deposited to the inner shell, or multiple shells including PU in an inner shell, hybrid PU/PBAE in a transitioning shell, and PBAE in an outer shell. Formation of the microcapsules includes polymerization between multifunctional amine and multifunctional acrylate to produce a water soluble PBAE; polymerization between polyisocyanate in oil phase and multifunctional amine in aqueous solution to produce PU microcapsule, polymerization between polyisocyanate and the amine moiety of PBAE prepolymer to produce hybrid PU/PBAE microcapsule wall; and polymerization between multifunctional acrylate and primary or secondary amine moiety of the PBAE prepolymer to form a PBAE outer shell.
