ABSTRACT:
Water soluble cellulose acetoacetates prepared by contacting a cellulose material with diketene, an alkyl acetoacetate, 2,2,6-trimethyl-4H-1,3-dioxin-4-one or a mixture thereof in a solvent system comprising lithium chloride plus a carboxamide. Compositions containing the cellulose acetoacetates and, optionally, a crosslinking agent are useful for coatings applications.
