Abstract:
Monomer solution and liquid solution immiscible with the monomers in the monomer solution are cocurrently jetted upwardly in a pulsating manner in a reaction vessel. Monomer droplets are allowed to rise up in a controlled and smooth manner under the dynamic forces exerted by differential flow rate and differential pressure between the monomer and liquid solutions and the differential densities between the monomer and liquid solutions without causing coalescence, agglomeration and breakup of the monomer droplets and to stabilize by partial polymerization of the droplets at 50-60° C. The monomer droplets flow out horizontally into a polymerization reactor and get polymerized in the polymerization reactor under agitation at 80-85° C. The polymer beads are dried at 80-100° C. and sieved.
