ABSTRACT:
The production of polymer beads by a suspension polymerization process in which a vinyl aromatic monomer having a free-radical generating catalyst dissolved therein is suspended in an aqueous medium with the aid of from 0.1 to 2.0 percent by weight, based on monomer, of a finely divided phosphate suspending agent in the presence of a modifier and heated to cause the monomer to polymerize into polymer beads is improved by the addition to the suspension of at least about 0.02 percent by weight based on monomer of certain aminoalkanesulfonic acids and N-substituted derivatives thereof. The process of the invention is especially applicable in the preparation of large polymer beads.
