Abstract

A process for preparing polymer spherules based on polymerizing a polymerizable composition containing at least one vinyl aryl monomer while said polymerizable composition is suspended in water containing zinc oxide as a suspending agent, characterized in that polymerization is initiated while the aqueous phase of the suspension is at a pH value of at least 9.3 and said pH value is maintained above 7.0 throughout the polymerization.
