METHODS OF PREPARING VINYLIDENE CHLORIDE POLYMER COMPOSITIONS

摘要

The present invention relates generally to methods of preparing vinylidene chloride polymer compositions. In one embodiment, a method of preparing a vinylidene chloride polymer composition comprises (a) adding a first dispersion comprising a wax, a polyolefin or a combination thereof to an aqueous dispersion comprising vinylidene chloride polymer particles; (b) adding an acrylic polymer latex to the aqueous dispersion; and (c) coagulating the wax, the polyolefin, or the combination of the wax and polyolefin, and the acrylic polymer on the surface of the polymer particles.
