Abstract
Abstract Polymer particles in which polysiloxane is composed is disclosed. The polymer particles are prepared by condensing at least one organosilane compound in the presence of organic polymer particles which are prepared from specific monomers and dispersed in an aqueous medium. The polymer particles possess excellent water resistance, weatherability, water repellency, adhesion, and flexing resistance, and thus are useful as water paints, coating agents, carpet packing material, floor polishing agents, cementing medium, and the like.
