Improvements in the synthesis of porous polymers for different applications have been carried out in our laboratory. Beads of poly(styrene‐co‐divinylbenzene) with morphology adequate to the application at hand were prepared. Packing materials for size exclusion chromatography (SEC) weve prepared by single‐step swelling and polymerization (SSWP) and by modified suspension polymerization (MSP). High values of exclusion limit (10 6 and 8.0x10 6 ) were attained for SEC columns packed with poly(styrene‐co‐divinylbenzene) synthesized using high proportions of polystyrene, as porogen agent and divinylbenzene. The maximum values of exclusion limits were attained for SEC columns packed with beads prepared by SSWP method.
