Curable compositions.

摘要

New and improved curable compositions useful as non-yellowing, acid resistant coatings for a variety of substrates and as adhesives and binders are disclosed. The curable compositions comprise a polymeric component comprising poly(C1-C6 alkyl acrylamidoglycolate) functional units and poly (active hydrogen) functional units and preferably an effective amount of a protic acid crosslinking catalyst. In preferred embodiments acid-catalyzed room temperature curable coating compositions are provided. The compositions may be cured effectively at lower temperatures without the use of amines or other toxic crosslinking agents and do not liberate formaldehyde on curing. A method for making poly(C1-C6 alkyl acrylamidoglycolate) functional polymers is also disclosed.
