Claim 11:
12. 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 metal fatty acid dispersion to a portion of the surfaces of polymer particles to form dispersion-coated polymer particles;
B) applying the aqueous polysiloxane emulsion to a portion of the surfaces of the dispersion-coated polymer particles to form emulsion-dispersion-coated polymer particles;
C) drying the emulsion-dispersion-coated polymer particles to form the coated polymer particles; and
wherein, optionally, the dispersion-coated polymer particles from step A are dried, before step B.
