    摘要: A process to form coated polymer particles comprising polymer particles formed from a polymer composition comprising an olefin-based polymer, and a coating formed from a coating composition comprising an aqueous metal acid dispersion and an aqueous polysiloxane emulsion, said process comprising the following: mixing together the aqueous metal acid dispersion and the aqueous polysiloxane emulsion to form a dispersion/emulsion mixture; applying the dispersion/emulsion mixture to a portion of the surfaces of the polymer particles to form wet-coated polymer particles; drying the wet-coated polymer particles to form the coated polymer particles. The aqueous metal acid dispersion and the aqueous polysiloxane emulsion may also be applied, individually, in separate steps.
