ABSTRACT:
The suspension polymerization of acrylic acid esters, methacrylic acid esters and vinyl aromatics alone or in admixture with subordinate amounts of other monomers is carried out in the presence of an acrylic or methacrylic acid homo or polymerizate or its alkali metal or ammonium salts as dispersing agent with the addition of an acid ester of phosphoric acid with an alkanol having 1 to 8 carbon atoms. The size of polymerizate beads produced is influenced by this procedure.
