Abstract
Porous, polymer particles comprising a functionalized cross-linked copolymer having microporous regions and macroporous regions in the polymer matrix thereof, wherein the functional groups are essentially present only within the macroporous regions, as well as processes for preparing these particles based on a template polymerization technique followed by removal of the template polymer from the particles are disclosed. The particles of the invention are useful in chromatography, and in various analytical, diagnostic techniques and solid state peptide, DNA synthesis.
