METHOD OF PRODUCING MONOMER DROPLETS |
摘要 |
A method of producing monomer droplets dispersed in an aqueous medium is provided, comprising providing an apparatus comprising a metallic membrane having a plurality of holes; wherein a monomer phase is in contact with a first side of said membrane; wherein an aqueous medium is in contact with a second side of said membrane; wherein said aqueous medium comprises one or more surfactant; and conveying said monomer phase through said through holes into said second volume under conditions sufficient to form a plurality of monomer droplets; wherein a shear force is applied at a point of egression of the first volume into the second volume; wherein the direction of shear is substantially perpendicular to the direction of egression of the first volume. Also provided is a method of making polymer particles comprising producing monomer droplets and then polymerizing some or all of the monomer in said monomer droplets. |
