A process for the preparation of aqueous dispersion of finely divided inorganic solid and addition polymer compound particles, aqueous dispersion of composite particles, use of aqueous dispersion of composite particles, and powder of composite particles.

摘要

A process for preparing an aqueous dispersion of composite particles composed of addition polymer and finely divided inorganic solid, in which process at least one ethylenically unsaturated monomer is dispersely distributed in aqueous medium and is polymerized by the method of free-radical aqueous emulsion polymerization by means of at least one free-radical polymerization initiator in the presence of at least one dispersely distributed, finely divided inorganic solid and at least one dispersant.
