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.

Abstract: The present invention relates to aqueous polymer dispersion of voided polymer particles and to a process for preparing such aqueous polymer dispersions. The present invention also relates to polymer particles, in particular powders of said polymer particles, which are obtained by drying a polymer dispersion. Further aspects of the present invention relate to the use of such voided polymer particles and the polymer dispersions as opacifiers and to paints containing such aqueous polymer dispersions. The voided polymer particles comprise: i) an alkali swellable polymer core of polymerized ethylenically unsaturated monomers M(i) comprising polymerized acid monomers M(i.ac) in an amount sufficient for allowing the polymer core to swell at a pH of at least pH 7.5; ii) an intermediate polymer layer of polymerized ethylenically unsaturated monomers M(ii); and iii) a polymer shell of polymerized ethylenically unsaturated monomers M(iii) having a theoretical glass transition temperature according to Fox of at least 60°C. where the monomers M(iii) comprise at least 10% b.w., based on the total weight of the monomers M(iii), of one or more monomers M(iii.a) whose homopolymers have a glass transition temperature of at least 50°C, where the monomer M(iii.a) is selected from the group consisting of C
