We have recently reported a pioneering study on ground organic monolith particles as new chromatographic separation media in our laboratory. The reaction mixture was composed of methacrylic acid (MAA) as funtional monomer, Trimethylolpropane trimethacrylate (TPTM) as crosslinker, azobis-isobutyronitrile (AIBN) as initiator, polyethyleneglycol as special porogen, and toluene- Isooctane mixture as solvent. In this study, we have prepared different stationary phases by changing formulation of reaction mixture and reaction temperature in a variety of different ways. For example, xylene and n-octane were used as new solvent to increase the reaction temperature. The key idea of this approach is to make soft monoliths with large pore volumes for easy pulverizing. The variations of morphology and chromatographic separation performance of the resultant organic monolith particles will be comparatively discussed.
