Thermosetting polyester beads in the size range of 200 to 2000 μm were prepared in a PVAl stabilized suspension polymerization system from a commercial unsaturated polyester resin. Bead size distribution curves were determined and the average surface mean diameter D m was calculated. Agitation speed, resin volume fraction in the reaction medium and PVAl concentration were varied and their effect on D m was studied.
