Abstract
Process for the production of polymers of vinylaromatic monomer compounds by means of the suspension polymerization system, in which an aqueous suspension of the monomer, a polymerization initiator and a suspending agent are polymerized under heating, characterized in that for the production of flat beads, a hydroxyethyl cellulose is used as a suspending agent in an amount not sufficient to suspend the monomer or the polymer, respectively, and also a synergistic amount of an alkali metal salt of a phosphoric acid of the following formulas ** (See formula) ** where n is an integer having a value from 0 to 5 and the pH of a 1% solution is greater than 8.5.
