Development of new style chromatographic packing materials and improvement of their performance are important in the study of chromatography. First, a new monolithic column of poly(vinyl ester resin-co-ethylene dimethacrylate) has been prepared by in-situ copolymerization of the monomers in the presence of porogenic diluents. The main factors affecting the porous structure and the loading of hydroxyl groups of the monolithic columns were investigated. In order to evaluate the mechanical stability of ...
