In this study, nonswellable and swellable poly(ethylene glycol‐dimethacrylate) microspheres, in the size range of 20–177 μm, were produced by conventional and modified suspension polymerizations of ethylene glycol‐dimethacrylate (EGDMA) in an aqueous medium. Poly(vinyl alcohol) and benzoyl peroxide were used as the stabilizer and the initiator. A diluent, i.e., toluene, was included in the polymerization recipe of the modified suspension polymerization. The microspheres were characterized by optical microscopy, FTIR, and FTIR‐DRS. Highly crosslinked, transparent, and nonswellable poly(EGDMA) microspheres were obtained with the conventional suspension polymerization procedure. While the modified suspension polymerization provided swellable, opaque, and crosslinked copolymer microspheres. © 1996 John Wiley & Sons, Inc.
