1. A composition comprising ingredients (A) and (B): where Ingredient (A) is a catalytically effective amount of a catalytically active reaction product of a reaction of a Zr precursor and a ligand, where the Zr precursor is distinct from a reaction product of the Zr precursor and the ligand, the Zr precursor has formula Zr-A4, where each A is a monovalent hydrocarbon group, and the ligand is selected from the group consisting of ligands (1), (3), (4), (11), (14), (15) (27) and (29), shown below, (27) a ligand of general formula (iii) where each A6 is independently selected from halogen atom and a monovalent hydrocarbon group, subscript d is an integer from 0 to 4, Q3 is a carboxylic acid group, and Q4 is selected from a carboxylic acid group, OH, and a group of formula PA7A8, where A7 and A8 are each independently selected from H, a halogen atom, an alkyl group, an aryl group, and an aralkyl group; or (29) a ligand of general formula (v) where subscript f is an integer from 0 to 4, subscript g is an integer from 0 to 4, each A10 and each A11 are independently selected from a monovalent hydrocarbon group and a monovalent halogenated hydrocarbon group, subscript h is an integer from 1 to 6, each Q5 is independently selected from O, P, and S; and Ingredient (B) is a silicon containing base polymer having an average, per molecule, of one or more hydrolyzable substituents, and Ingredient (A) is capable of catalyzing a condensation reaction of the hydrolyzable substituents on ingredient (B). |
