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, and the ligand is selected from the group consisting of ligands (1) to (17), (21) to (23), (25) to (27) and (29) to (34), shown below,or
(26) a ligand of general formula (ii) where subscript a is 0 or 1, subscript b is an integer from 0 to 4, subscript c is an integer from 0 to 4, A1 is selected from Hand a monovalent hydrocarbon group, each A2 and each A3 is independently a monovalent hydrocarbon group, Q1 is selected from N and a group of formula CA4, where A4 is H or a monovalent hydrocarbon group, Q2 is selected from OH and a group of formula SA5, where A5 is selected from H and a monovalent hydrocarbon group; or (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, H, a monovalent hydrocarbon group, 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 a 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, S, and CH2; or (30) a ligand of general formula (vi) where A12 is H or a monovalent hydrocarbon group, and each of A13, A14, and A15 is independently selected from H and a monovalent organic group, with the proviso that optionally, two of A13, A14, and A15 can be bonded together to form a fused heterocyclic group; or (31) a ligand of general formula (vii) where subscript i is an integer from 0 to 4, subscript j is an integer from 0 to 4, each A16 is independently a monovalent hydrocarbon group, each A17 is a monovalent organic group, A18 and A19 are independently selected from H and a monovalent hydrocarbon group, A20 is H an alkyl group, and A21 is H or an alkyl group; or (32) a ligand of general formula (viii) where A24 is a heteroatom selected from O and S, subscript k is an integer from 0 to 4, each A27 is independently selected from a halogen atom and a monovalent organic group, A22 is a monovalent hydrocarbon group, A23 is H or a monovalent hydrocarbon group, and A25 is a monovalent organic group; or (33) a ligand of general formula (ix) where A31 is a heteroatom selected from O and S, subscript m is 0 to 4, each of A28, A29, and A30 is independently a monovalent hydrocarbon group; or (34) a ligand of general formula (x) where a bond with ‘Rn’ represents a covalent single bond or an aromatic bond forming part of a ring structure, each of A39, A40, A41, A42, A43, and A44 is independently selected from H and a monovalent organic group, with the proviso that optionally A42 and A43 may be bonded together to form a ring structure selected from a carbocycle, an aryl group, an aralkyl group or a heterocyclic group, A45 is either a monovalent hydrocarbon group or a divalent linking group, with the proviso that when A45 is a divalent linking group, then A45 links the structure of general formula (x) with a structure of general formula (xi) where * denotes a point of attachment; 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). |
