Abstract

1,050,135. Copolymers of isobutyraldehyde and a vinyl ether. BADISCHE ANILIN- & SODA-FABRIK A.G. March 4, 1964 [March 20, 1963], No. 9065/64. Heading C3P. Isobutyraldehyde and a vinyl ether are copolymerized in a non-proton-active organic solvent at below 0‹ C. in the presence of an ionic catalyst. Preferred ethers are isobutyl vinyl ether, methyl and ethyl vinyl ether, and dipropyl vinyl ether, while Friedel-Craft and organoaluminium compounds are particularly preferred catalysts, e.g. boron trifluoride, aluminium tetrachloride. Specified solvents are aliphatic hydrocarbons, halohydrocarbons and aliphatic ethers. The monomers may be added continuously at the same or different rates or separately during sequential periods during the polymerization-the vinyl ether being added during the last sequential period. More than one ether may be present.
