Abstract
A wax-polymer compound includes (a) a polymer component that is a polymerized unsaturated monomer, optionally copolymerized with a vinyl-aromatic monomer, and (b) a halogenated hydrocarbon wax component. The polymer component is grafted to the halogenated hydrocarbon wax component, and the wax-polymer compound has a number average molecular weight of about 1,000 to about 100,000. A method of making the wax-polymer compound and a coated silica particle are also disclosed.
