Abstract
A beaded polymeric adsorbent has a core part; a shell part arranged around the core part, with one of the parts having a lipophilic property and another of the parts having a hydrophilic property, and is produced by preparing an organic phase composed of water insoluble monounsaturated and poly unsaturated comonomers; preparing an aqueous phase composed of a mixture of water soluble monounsaturated and polyunsaturated comonomers; forming a dispersion of the organic phase and the aqueous phase in a single vessel; and creating conditions for first polymerizing of one of the phases which forms the core part and thereafter polymerizing the other of the phases which forms the shell part.
