Non-spherical polymer shaped micro channel type manufacturing method of the particles and the non-spherical polymer shaped particles.

摘要

PROBLEM TO BE SOLVED: To provide a microchannel manufacturing method for nonspherical, definite-shape polymer particles, wherein the definite-shape polymer particles each having a nonspherical shape such as semisphere, disc, or dumbbell are manufactured continuously, and the nonspherical, definite-shape polymer particles.;SOLUTION: An oily fluid 6a of a polymerization-curable resin component and a noncurable oily fluid 6b are transferred through a first microchannel 1 as an O-phase continuous fluid phase to form multiple-split-phase fluid phases with at least not less than two split-phases, a discharged material 10 that is continuously or intermittently discharged into a spherical liquid droplet phase of a W-phase (or water-phase) 7 flowing in a second microchannel 2 is made to be spherical liquid droplets 12' of a primary formed material and discharged into the second microchannel 2, while it is being transferred in the spherical liquid droplet phase under an O/W type correlation, and then the non-curable oily fluid component 6b is exfoliated, in the course of the polymerization/curing of the polymerization-curable oily fluid resin component 6a, to form the nonspherical, definite-shape polymer particles as empty shells of the primary formed material.;COPYRIGHT: (C)2005,JPO&NCIPI
