POLYMERIC SUPPORT HAVING NOVEL PORE STRUCTURES

摘要

The invention is a method of producing a cross-linked polymeric support havi ng a multimodal pore structure, which comprises providing a degradable initiato r molecule; providing an organic phase comprising said initiator molecule, radically polymerisable monomers and a porogen in a solvent; providing an aqueous phase comprising a transition metal catalyst; suspension polymerisation of the organic phase by adding a ligand, co-ordinating to the transition metal in the aqueous phase to produce a cross-linked polymeric support having a primary pore structure and comprising initiator molecule; a nd subjecting the support obtained to degrading conditions to remove the initiator molecule from within the support to produce a cross-linked polymer ic support having a secondary pore structure in addition to the primary pore structure.
