摘要： Method for preparing surface-functionalized 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 core particles starting from at least one monomer or oligomer in an emulsion polymerization under starved conditions;
b) synthesis of a shell layer on the surface of the primary core particles to form core-shell particles starting under starved conditions from the same at least one monomer or oligomer as in step a) and in addition to that at least one additional azide monomer;
c) swelling of the core-shell particles with a liquid comprising at least one of the monomers or oligomers as used in a) as well as a polymerization initiator but preferably no azide monomer in particular not the additional azide monomer from step b);
d) formation of agglomerates of the particles by application of shear;
e) polymerization of the agglomerates to form the macro porous micro-clusters;
f) direct or indirect surface-functionalization of the agglomerates by way of Cu-(I)-catalyzed or strain promoted azide-alkyne cycloaddition with the azide introduced in step b).
