ACETYLACETOXYALKYL-ALLYL ETHERS,THEIR MANUFACTURE |
摘要 |
Unsaturated acetoacetic acid esters are suitable as comonomers in the polymerization of unsaturated compounds in an aqueous medium. Particularly suitable are acetylacetoxyalkyl-allyl ethers which may be synthesized in an easy manner and correspond to the formulae <IMAGE> or <IMAGE> 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 DEG to 100 DEG 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. |
