(57) [Summary]nThe present invention relates to a method for producing a microsphere of a porous polymer. According to the invention, the polymer, preferably a polyolefin or PVC, is dissolved in a solvent, preferably a halogenated hydrocarbon or alkyl ester, at a temperature approximately close to the boiling point of the solvent. The hot polymer solution is cooled, and the polymer spherules formed during the cooling process are separated, washed and dried. Porous polymer microspheres are suitable, for example, as catalyst carriers or adsorbents. |
