摘要:
The present invention provides methylene beta-ketoester monomers, methods for producing the same, and compositions and products formed therefrom. In the method for producing the methylene beta-ketoesters of the invention, a beta-ketoester is reacted with a source of formaldehyde in a modified Knoevenagel reaction optionally in the presence of an acidic or basic catalyst, and optionally in the presence of an acidic or non-acidic solvent, to form reaction complex. The reaction complex may be an oligomeric complex. The reaction complex is subjected to further processing, which may be vaporization by contact with an energy transfer means in order to isolate the beta-ketoester monomer. 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).
