Porous/hollow polymer microparticles were prepared by suspension polymerization from a resol, water‐soluble phenolic resin in a multiple emulsion system oil‐in‐water‐in‐oil(O/W/O). The porous/hollow structures of phenolic resin microparticle were characterized by optical microscopy (OM) and scanning electron microscopy (SEM). It is shown that the porous/hollow structure is related to a dispersion and curing process of the resol resin. It was indicated that it is low‐cost and simple to prepare porous/hollow phenolic resin micr‐particles from resol in an O/W/O system. Copyright © 2007 John Wiley & Sons, Ltd.
