Abstract

The present invention relates to a method of producing one or more macroporous cross-linked polymer particles, which comprises polymerization and cross-linking of divinyl ether monomers in an inert solvent, in which method the polymerization is free radical initiated. The invention also relates to particles so produced, which are useful as separation medium e.g. in RPC or, after suitable derivatization, in other chromatographic methods.
