  • Patent number: 9938390
    Abstract: A method for producing macro porous micro-clusters is proposed comprising at least the following individual steps in given order: a) synthesis of dispersed cross-linked polymeric latex primary particles starting from at least one monomer or oligomer using emulsion polymerization; b) swelling of the primary particles with a liquid comprising at least an additional charge of monomer and/or oligomer and a cross-linker, optionally further comprising functionalization agents; c) destabilization by increase of ionic strength (by adding a salt and/or acid and/or base) in a combination with application of shear, both being above the gel formation boundary of the phase diagram, until agglomerates composed of primary particles of the desired size are formed; d) polymerization of the agglomerates to form the macro porous micro-clusters. Furthermore the invention to relates to correspondingly produced micro-clusters and uses of such micro-clusters in particular for chromatographic purposes.
