Abstract
A crosslinking composition includes a compound having at least two functional groups that are each independently represented by Chemical Structure (I): X is an oxygen, sulfur, or nitrogen; R1 is an alkyl group, an aryl group, or an alkylaryl group; R2, R3, and R4 are each independently an alkyl group, an aryl group, an alkylaryl group, or a hydrogen; R5 is an alkyl group, an aryl group, an alkylaryl group, or a hydrogen; z is 0 when X is oxygen or sulfur and z is 1 when X is nitrogen; and when a double bond is formed between a carbon atom bonded to R3 and an adjacent nitrogen, m is 0, and when a single bond is formed between the carbon atom bonded to R3 and the adjacent nitrogen, m is 1.
