Methylene β-ketoester monomers, methods for producing methylene β-ketoester monomers, polymerizable compositions and products made therefrom

摘要

The present invention provides methylene β-ketoester monomers, methods of making the same, compositions and products made therefrom. In the process for producing the methylene β-ketoester of the present invention, the β-ketoester precursor is optionally converted in a modified Knoevenagel reaction in the presence of an acidic or basic catalyst, optionally in the presence of an acidic or non-acidic solvent. React with formaldehyde source to make reaction complex. The reaction complex may be an oligomer complex. The reaction complex may be vaporized by contact with an energy transfer means for further processing and isolating the β-ketoester monomer. The present invention further includes monomer-based products (eg, inks, adhesives, coatings, sealants or reactive molds) and polymer-based products (eg, fibers, membranes, sheets, medical polymers, composite polymers and surfactants). And compositions and products made from the methylene β-ketoester monomers of the present invention.
