    Abstract: A process for separating, by distillation, a mixture consisting essentially of 3,3-dimethylacrolein and 3-methyl-3-buten-1-ol, wherein the mixture to be separated is distilled in the presence of water and glycerol, the 3,3-dimethyl-acrolein first being distilled off azeotropically with water and the 3-methyl-3-buten1-ol then being separated, as an azeotropic mixture with water, from the higher-boiling glycerol. It is also possible to isolate the 3,3-dimethylacrolein by distillation if the 3-methyl-3-buten1-ol is partially replaced by 3-methyl-2-buten-1-ol. The 3,3dimethylacrolein, which can be isolated in pure form by the process of the invention, is a valuable intermediate for the synthesis of natural substances such as citral, vitamin A and chrysanthemic acid.

    Abstract: Stabilized polyolefin molding materials comprising:- (1) a polyolefin; (2) a stabilizer; and optionally (3) one or more conventional other auxiliaries or additives and containing certain 4-(m,m''-ditert.-butyl-p-hydroxyphenyl)-butyl- (2) compounds as stabilizers. The polyolefins exhibit better stability than prior art stabilized polyolefins.

    Abstract: High molecular weight polymers are prepared by polymerizing butene-1-ine-3 and/or a 2-alkyl, 2-cyclo-alkyl or 2-aryl derivative thereof by high energy ionizing radiation and/or by means of a metal carbonyl which has been activated by ultra-violet or other high energy radiation. Specified monomers are unsubstituted vinyl acetylene and the 2-methyl, 2-ethyl, 2-n-butyl, 2-hexyl, 2-cyclohexyl and 2-phenyl derivatives. Up to 50 mole per cent of an ethylenically unsaturated comonomer, e.g. butadiene, isoprene, acrylonitrile, methacrylonitrile and styrene, may also be present. The metal carbonyl may be of chromium, tungsten, iron, molybdenum, manganese, cobalt or rhenium, e.g. manganese decacarbonyl, chromium hexacarbonyl, diiron enneacarbonyl, molybdenum hexacarbonyl or cyclopentadienyl manganese tricarbonyl. Polymerization may be effected in the presence of stabilizers, e.g. substituted phenols, to prevent premature cross-linking. In examples (1) 2-methylbutene-1-ine-3 and (2) a mixture thereof with acrylonitrile are polymerized by irradiation in the presence of di-t.-butylphenol; (3) 2-cyclohexylbutene -1-ine-3 is polymerized in hexane in the presence of cobalt tetracarbonyl, nickel tetracarbonyl and ultraviolet light; and 2-phenylbutene-1-ine-3 is polymerized in benzene in the presence of ultra-violet light and (4) tungsten hexacarbonyl and (5) molybdenum hexacarbonyl. The products may be compounded with carbon black, zinc oxide, stearic acid, hydrocarbons, phenyl b -naphthylamine, sulphur and cyclohexylmercaptobenzothiazole and vulcanized.
