Kurzfassung:
Supermacroporous monolithic polyacrylamide (pAAm)‐based columns have been prepared by radical cryo‐copolymerization (copolymerization in the moderately frozen system) of acrylamide with functional co‐monomer, allyl glycidyl ether (AGE), and cross‐linker N,N ´‐methylene‐bis‐acrylamide (MBAAm) directly in glass columns (ID 10 mm). The monolithic columns have uniform supermacroporous sponge‐like structure with interconnected supermacropores of pore size 5–100 μm. The monoliths can be dried and stored in the dry state. High mechanical stability of the monoliths allowed sterilization by autoclaving. Column‐to‐column reproducibility of pAAm‐monoliths was demonstrated on 5 monolithic columns from different batches prepared under the same cryostructuration conditions.
