US 9,969,822 B2 · Multifunctional monomers, methods for making multifunctional monomers, polymerizable compositions and products formed therefrom

Abstract

The present invention provides multifunctional monomers, including, but not limited to include multifunctional methylene malonate and methylene beta-ketoester monomers; methods for producing the same; and compositions and products formed therefrom. The multifunctional monomers of the invention may be produced by transesterification or by direct synthesis from monofunctional methylene malonate monomers or methylene beta-ketoester monomers. The present invention further compositions and products formed from methylene beta-ketoester monomers of the invention, including monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants).

Claims6

Dependent claims
