Abstract
A variety of methods to prepare a polymer composition containing at least one polymer and at least one modified pigment are described. The methods, in part, involve introducing a slurry containing at least one modified pigment into an emulsion or solution polymer prior to dewatering. Other polymer systems can be used including aqueous based polymerizations and solvent-based polymerizations, which can include free radical polymerizations. Other methods involve the formation of a modified pigment in the presence of an emulsion or solution polymer and then recovering the polymer composition containing the modified pigment. Compositions containing at least one modified pigment and the emulsion or solution polymer are also described as well as uses for the polymer compositions of the present invention.
