Liquid oligomers containing acrylate unsaturation
-
, (2008/06/13)
The liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate functional donor compounds with multifunctional acrylate receptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from >/=1:1 to >/=13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate. Unuseable gelled or solid oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.

The diketene/acetone adduct, 2,2,6-trimethyl-4H-1,3-dioxin-4-one, efficiently acetoacetylates aliphatic and aromatic alcohols, amines, and thiols.These acetoacetylation reactions are fast and stoichiometric, require no catalysis, and give only volatile byproducts.
