Abstract:
1. A catalyst composition comprising: (a) at least 30 percent by weight of a catalyst compound based on the total weight of solids in the catalyst composition; and (b) a polymer prepared from ethylenically unsaturated monomers, wherein: (i) the polymer has a backbone derived from substantially hydrophilic monomers and/or monomers containing groups that may be rendered substantially hydrophilic after polymerization, and a plurality of side chains along the backbone derived from substantially hydrophobic monomers, or (ii) the polymer has a backbone derived from substantially hydrophobic monomers and a plurality of side chains along the backbone derived from substantially hydrophilic monomers and/or monomers containing groups that may be rendered substantially hydrophilic after polymerization; and wherein the catalyst compound is contained within or encapsulated by the polymer.
