PROCESS FOR PRODUCING HYDROPHOBIC LIQUID DROPLET, PROCESS AND APPARATUS FOR PRODUCING POLYMER BEAD AND PROCESS FOR PRODUCING ION EXCHANGE RESIN

摘要

PROBLEM TO BE SOLVED: To provide a process for stably producing a polymer bead of high uniformity in particle size on an industrial scale by means of simple equipment without need of the strict control of flow rate of liquids and without accompanying the generation of heat, problems in the aspect of safety or the like while theoretically preventing the development of liquid droplets having a large particle size by uniting the liquids together. SOLUTION: The process for producing the polymer bead comprises introducing a hydrophobic liquid containing polymerizable monomers and a hydrophilic liquid respectively through separate liquid inlet passages and permitting the hydrophobic liquid and the hydrophilic liquid to join and mix with each other within a channel structure wherein a plurality of liquid inlet passages join and lead into one liquid outlet passage, discharging the resultant mixed liquid through the liquid outlet passage into an aqueous medium and dispersing the hydrophobic liquid contained in the mixed liquid into the aqueous medium to thereby produce liquid droplets comprising the hydrophobic liquid and further polymerizing the polymerizable monomers contained in the liquid droplets.
