The present document relates to a method for producing macro-porous materials comprising the following steps: a) synthesis of narrowly dispersed cross-linked polymeric particles starting from a monomer and a cross-linker in an emulsion polymerization; b) swelling of the particles with a liquid comprising at least an additional charge of monomer and cross-linker and subsequent destabilisation; c) initiating the reaction of the swelled particles to form a monolithic structure. The corresponding monolithic structures can be very efficiently functionalised if after the synthesis of the polymeric particles in step a) and before the initiation of the reaction of the swelled particles in step c) the polymeric particles are chemically functionalised or prepared for subsequent functionalization of the monolithic structure.
