| abstract |
A process for producing porous polymer beads in which polymers, preferably polyolefins or polyvinyl chloride, 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 beads formed during the cooling process are separated, washed and dried. The porous polymer beads are useful, for example, as catalyst carriers or as adsorption agents. |
