Abstract
A catalyst composition is provided. The composition comprises at least 30 percent by weight of a catalyst compound based on the total weight of solids in the catalyst composition; and a polymer prepared from ethylenically unsaturated monomers. The polymer either (i) 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) 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. The catalyst compound is contained within or encapsulated by the polymer. Methods of preparing the catalyst composition and curable compositions containing the catalyst composition are also provided.
