2-(Methacryloyloxy)ethyl acetoacetate

AAEM is a specialty methacrylic monomer with three available sites for chemical reaction. AAEM is used to formulate high solids solution acrylic resins and acrylic emulsions for lower VOC emission high performance industrial and architectural coatings. The methacrylic functionality may be used to react AAEM into an acrylic polymer backbone, leaving an acetoacetyl group pendant to the polymer chain. This pendant group contains the two reactive sites which may be used to add substituents to the polymer or for cross-linking. Many reactions can be carried out at these sites.  The chemistry of AAEM provides many new options for designing acrylic copolymer systems.
