ABSTRACT:
Particle size of suspension polymer particles is controlled in the suspension polymerization of a mixture of ethylenically unsaturated monomers including an ethylenically unsaturated monocarboxylic acid and pentaerythritol triacrylate by increasing the proportion of pentaerythritol triacrylate in said monomer mixture to increase the size of the suspension polymer particles.
