Copolymers of isobutyl 4,4′‐diphenylmethane dimethacrylate and divinylbenzene in the form of microspheres were obtained. For their preparation, the following techniques of heterogeneous polymerization were used: suspension polymerization, suspension–emulsion polymerization, and precipitation polymerization. Among the obtained microspheres, those synthesized by suspenson–emulsion polymerization were of a size suitable for high‐performance liquid chromatography, whereas the product of suspension polymerization could be used as a packing material for gas chromatography. Their porous structure was studied in details. The influence of the polymerization technique on the particle size and morphology was examined. © 2004 Wiley Periodicals, Inc.
