Abstract:
1. A composition comprising ingredients (A) and (B): where Ingredient (A) is a catalytically effective amount of a reaction product of a Zn precursor and a ligand, where the Zn precursor is distinct from a reaction product of the Zn precursor and the ligand, and where the ligand is selected from the group consisting of Ligands (a), (b), (c), and (d), where Ligand (a) has general formula (ii) where a bond with ‘Rn’ in the formula represents a covalent single bond or an aromatic bond forming part of a ring structure, Q 1 is a heteroatom selected from O and S, each A 2 and each A 3 is independently selected from a hydrogen atom and a monovalent hydrocarbon group, each of A 5 and A 6 is independently selected from a hydrogen atom and a monovalent organic group, with the proviso that A 5 and A 6 may be bonded together to form a ring structure, each of A 4 and A 7 is independently selected from nothing, a hydrogen atom, and a monovalent organic group, A 1 is either a monovalent hydrocarbon group or a divalent linking group, with the proviso that when A 1 is a divalent linking group, then A 1 links the structure of general formula (ii) with a structure of formula (iii): where * denotes a point of attachment, and Q 1 , A 2 , A 3 , A 4 , A 5 , A 6 , and A 7 are as defined above; Ligand (b) is Ligand (c) is and Ligand (d) is 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).
