Zusammenfassung:	A vinyl acylanhydrocitrate of the formula in which R denotes hydrogen or lower alkyl is disclosed. The vinyl acylanhydrocitrates can be prepared by initially contacting citric acid with a carboxylic anhydride or carbonyl chloride followed by transesterification of the reaction product either with vinyl acetate in the presence of a catalyst or with acetylene. The vinyl acylanhydrocitrates can be polymerized or copolymerized to form useful products useful for inclusion in adhesive compositions, for crosslinking in coating systems and duromers or, after ring opening with bases, as dispersing auxiliaries or agents to increase the viscosity of aqueous systems.
