Abstract
Styrenic polymer particles having a uniform particle size distribution are prepared without the formation of fine polymer powders. The suspension polymerization process which comprises providing a stirred, aqueous suspension of polymeric seed particles, adding gradually to the suspension styrenic monomer and polymerizing it therein, and continuing the addition of monomer as the polymerization proceeds, may be improved by introducing the styrenic monomer below the surface of the suspension.
