ABSTRACT:
Uniform polymer particles in a spherical form, having a three dimensional network structure, wherein not less than 80% by volume of the whole particles have a particle size within the range of .+-.20% of the volume average particle size of said uniform polymer particles, and said uniform polymer particles do not include particles having a particle size of not more than 5% of the volume average particle size, a process for preparing the uniform polymer particles, an apparatus suitable for use in the process, and a method of direct extracorporeal hemo-perfusion treatment using the uniform polymer particles. The uniform polymer particles of the present invention can be also used in various uses such as a parent material for an ion exchange resin, an adsorbent, and a packing material for a chromatography.
