| abstract |
A method of producing open porous spherical particles by polymerizing monovinyl monomers and divinyl monomers and/or polyvinyl monomers (cross-linkers) in an emulsion with the aid of an initiator. The method is characterized by the steps of (i) preparing a w/o/w emulsion which comprises an aqueous phase having emulsified therein droplets which contain a water-in-oil emulsion, wherein the oil phase in the droplets includes vinyl monomers and an emulsifier which provides an inverse emulsion and the droplets have a diameter smaller than 2,000 νm, and wherein the total amount of water is between 75-99 % (w/w); and (ii) thereafter initiating polymerization and isolating the particles, optionally after sieving, from the reaction mixture after the polymerization process. A population of open spherical porous polymer particles which have a diameter within the range of 50 νm-2,000 νm and include a pore system comprising (a) spherical hollows whose diameters are < 1/9 of the particle diameter; and (b) connecting pores whose opening diameters to the spheres and on the particle surfaces are about 1/10-1/3 of the diameter of the spheres. |
