    摘要: Water-borne cross-linking polymeric compositions and related embodiments, such as methods of making and using the compositions, as well as products formed with said compositions are described. The water-borne composition may comprise one or more polymers formulated from one or more monomers of which at least one is a monomer that yields acetaldehyde as a hydrolysis product, and incorporating cross-linking functionality such as, but not limited to, carbonyl or epoxy functionality, and a blocked cross-linking agent, for example, a hydrazone. Neither the cross-linking functionality nor the acetaldehyde reacts with the blocked cross-linking agent; however, the blocked cross-linking agent is capable of conversion to an alternative form cross-linking agent such as, but not limited to, a hydrazide, to yield a cross-linked polymer. The alternative form cross-linking agent may be formed in an equilibrium reaction including the blocked cross-linking agent.
