Coated olefin-based polymers with reduced blocking

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 fatty acid dispersion, and an aqueous polysiloxane emulsion, said process comprising the following:

• A) applying the aqueous polysiloxane emulsion to a portion of the surfaces of polymer particles to form emulsion-coated polymer particles;
• B) applying the aqueous metal fatty acid dispersion to a portion of the surfaces of the emulsion-coated polymer particles to form dispersion-emulsion-coated polymer particles;
• C) drying the dispersion-emulsion-coated polymer particles to form the coated polymer particles;
• and
• wherein, optionally, the emulsion-coated polymer particles from step A are dried, before step B.
