Abstract:
1. A composition comprising: particulates at least partially coated with a polymer solution comprising a polymer and a polar, aprotic solvent, wherein the polymer is not substantially soluble in water and wherein the polymer is present in the polymer solution in an amount from 25% to about 75% by weight of the polymer solution; and wherein the polymer comprises at least one polymer selected from the group consisting of: a polyacrylonitrile, a copolymer of acrylonitrile and methyl acrylate, a copolymer of acrylonitrile and methyl methacrylate, a copolymer of acrylonitrile and vinyl chloride, a copolymer of acrylonitrile and butadiene, a polyacylate, a polymethacrylate, a poly(vinyl alcohol); and an aqueous medium.
