A COAT POLYMERIC PARTICULATE, AND A PROCESS FOR COATING A POLYMERIC PARTICULATE

摘要

The instant invention is a coated polymeric particulate, and a process for coating a polymeric particulate. The coated polymeric particulate includes a polymeric particulate; and a coating composition present on at least a portion of at least one surface of the polymeric particulate. The coating includes an interconnected media; and at least one discrete island at least partially embedded in the interconnected media. The process for coating a polymeric particulate includes the following steps: (1) selecting a polymeric particulate; (2) selecting an aqueous dispersion comprising (a) a small particle component, wherein the small particle component comprises a polyolefin polymer having an average particle size in the range of 0.02 to 0.15 µm; (b) a large particle component, wherein the large particle component comprises a polyolefin polymer having an average particle size in the range of 0.3 to 0.8 µm; and (c) water; (3) applying the aqueous dispersion to the polymeric particulate; (4) thereby coating the polymeric particulate.
