Abstract: The present invention relates to a composition comprising an aqueous dispersion of polymeric composite microspheres comprising an aqueous dispersion of polymeric composite microspheres that comprise a polysiloxane and a polymer, as defined herein, and a suspension polymerization process for making the composition. The composition is useful for making defect free coatings with a relatively low coefficient of friction.

Abstract: The present invention relates to composition comprising an aqueous dispersion of microspheres and a class of a nonionic polyalkylene oxide of a distyryl or tristyryl phenol or an anionic polyalkylene oxide salt of a distyryl or tristyryl phenol and a process for preparing the composition. The microspheres have an average particle size in the range of from 1 μm to 25 μm, as well as a low coefficient of variation and low gel concentration; the composition is useful in coatings applications, especially where a matte finish is desired.
