摘要

HOE 79/F 171 ACETYLACETOXYALKYL-ALLYL ETHERS, THEIR MANUFACTURE AND USE of the disclosure: Unsaturated acetoacetic acid esters are suitable as comonomers in the polymerization of unsaturated compounds in an aqueous medium. Particularly suitable are acetylacetoxyalkylallyl ethers which may be synthesized in an easy manner and correspond to the formulae or Said allyl ether derivatives are especially prepared by reacting an allyl alcohol with an epoxide and reacting the resulting hydroxyalkyl-allyl ether with diketene, Both reaction steps are carried out at a temperature of from 0 to 100.degree.C, preferably in the presence of a catalyst, The allyl ether derivatives may be copolymerized especially with vinyl compounds, such as vinyl esters, acrylic acid esters olefins, vinyl halides and vinyl aromatic hydrocarbons.
