  • Patent number: 8378039
    Abstract: [Summary] The present invention relates to an apparatus for manufacturing polymer particles and a method for manufacturing the same. The present invention provides an apparatus and a method, by which polymer particles having excellent monodispersity and homogeneous physical properties, such as homogeneous cross-linking degree and polymerization degree, may be efficiently prepared. In the present invention, particles having excellent monodispersity with the desired particle diameter, and also having a high cross-linking degree or a core-shell or core-double shell structure may also be effectively prepared. In addition, the processes for manufacturing said polymer particles are exceptionally reproducible in the present invention.

  • Patent number: 7955564
    Abstract: The present invention discloses the substrate and the micro reactor for mixing two kinds of fluids. The micro reactor of the present invention comprises a housing having first and second inlet ports and an outlet port formed thereon; and a plurality of substrates stacked in the housing, wherein the substrate has a space formed at a central portion thereof in one direction; a plurality of first channels extended from one side thereof to the space and corresponding to the first inlet port; and a plurality of second channels extended from the other side thereof to the space and corresponding to the second inlet port; wherein a portion between two neighboring first channels corresponds to the second channel and a portion between two neighboring second channels corresponds to the first channel to form sequentially reaction interfaces of the first and second fluids in the space.

  • Patent number: 7510688
    Abstract: A stack type reactor that can adjust a length of channel (reaction time) to react raw substances with each other for a sufficient time and mix completely raw substances to maximize the reaction efficiency. The stack type reactor comprises an upper block with at least two inlets that introduce different kinds of raw substances and a lower channel fluidly connected to the inlets and formed at a lower surface thereof; a unit block including an upper channel corresponding to the lower channel of the upper block and formed on an upper surface thereof, the unit block including a lower channel formed at a lower surface thereof and fluidly connected with the upper channel via a connecting flow passage. The upper block and unit block form a flow path for the raw substances by connecting to the lower channel of the upper block to the upper channel of the unit block.
