The present invention provides methylene beta-diketone monomers, methods for producing them, and compositions and products formed therefrom. In the method for producing the methylene beta-diketones of the invention, a beta-diketone 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 a solvent. acidic or non-acidic, to form a reaction complex. The reaction complex may be an oligomeric complex. The reaction complex is subjected to further processing, which can be vaporization by contact with energy transfer means in order to isolate the beta-diketone monomer. Additional products and compositions of the present invention formed from methylene beta-diketone monomers include products based on monomers (for example inks, adhesives, coatings, sealants or reactive molding products) and polymer based products (for eg fibers, films, sheets, medical polymers, composite polymers and surface active agents). |
