ABSTRACT:
The invention relates to a method for producing monolithic molded elements e.g. as sorbents for chromatographic columns or capillary vessels. The aim of the invention is for said molded elements to be able to remain directly in the gel mold thereof following the production process. Said aim is achieved by the inventive method, according to which the surface of the gel mold is activated by etching, increasing the surface, or chemically modifying the surface before the gelling mold is filled with the monomer sol.
