A process is disclosed for producing porous polymer globules. Polymers, preferably polyolefins or PVC, are dissolved in a solvent, preferably halogenated hydrocarbons or alkyl esters, at temperatures close to the boiling point of the solvent. The hot polymer solution is cooled and the polymer globules formed during the cooling process are separated, washed and dried. The porous polymer globules are for example useful as catalyst carriers or as adsorbing products. |
