发明名称 Method of preparing spheroid polymer particles having a narrow size distribution by dispersion polymerization, particles obtainable by the method and use of these particles
摘要 The invention relates to a method of preparing spheroid polymer particles having a narrow size distribution by dispersion polymerization. This method comprises the steps of: providing a two-phase system in the form of a dispersion comprising an organic phase of droplets dispersed in an aqueous medium, mixing said organic phase in said aqueous medium under agitation without using a dispersion stabilizing agent to stabilize the dispersion, wherein the organic phase comprises at least a crosslinkable monomer, a polymerization initiator and an organic solvent for said monomer, and allowing the crosslinkable monomers to polymerize, while the two-phase system is agitated.
