METHOD FOR COVALENTLY ATTACHING POLYMERIC MONOLITHS TO POLYETHER ETHER KETONE (PEEK) SURFACES

摘要

Method for covalently attaching polymeric monoliths to polyether ether ketone (PEEK) surfaces The present invention provides a method of covalently attaching a polymeric monolith to the internal surface of polyether ether ketone (PEEK) tubing and column housings, comprising the steps of: (a) reducing the ketone group of the PEEK to a hydroxyl group to obtain a modified PEEK, (b) optionally reacting the hydroxyl group obtained in step (a) with a compound having an active vinyl group to form a modified PEEK selected from the group of acrylate modified PEEK, methacrylate modified PEEK, styrene modified PEEK and epoxy modified PEEK, and (c) reacting the modified PEEK obtained in step (a) or (b) with a polymer or polymerization mixture for forming the polymeric monolith. Hereby, the mechanical stability and solvent durability of larger diameter monolithic columns as well as their overall performance are improved.
