Abstract: The present invention provides a process for preparing emulsion polymer particles of a hollow core/shell structure in the presence of a monomer plasticizer having a ceiling temperature less than 181° C. wherein a polymerization inhibitor or reducing agent is not added to the aqueous emulsion of the core shell particles during the neutralization and swelling stage. The obtained core shell particles are useful in paints, paper coatings, foams, and cosmetics.
