摘要： A non-continuous suspension polymerization process for the production of finely-divided, low molecular weight polymeric particles of an aryl monomer is carried out in a heated aqueous suspension media at a polymerization temperature above the glass transition temperature of the desired polymer. The monomer reactants and the polymerization initiator are substantially simultaneously introduced into the heated suspension media at a slow, substantially continuous rate over a time within the range of from 20 to about 85 percent of the total polymerization reaction time. The suspension media is subjected to high-rate shearing throughout the reaction.
