Abstract

1,134,555. Alfin catalyst polymerization. NATIONAL DISTILLERS & CHEMICAL CORP. 17 Oct., 1966 [19 Oct., 1965], No. 46369/66. Heading C3P. Conjugated diolefinic hydrocarbons or hydrocarbons containing an olefinic bond conjugated with an aromatic ring, or methoxy derivatives thereof, are polymerized using a medium comprising a solvent containing at least 50% of at least one saturated branchedaliphatic hydrocarbon having 4 to 15 carbon atoms, a dihydroaromatic hydrocarbon molecular weight modifier and an alfin catalyst consisting essentially of a sodium alkoxide, a sodium alkenyl compound, and an alkali metal halide. The catalyst may be prepared by reacting, e.g. amyl chloride with sodium in pentane, and reacting the resulting amyl sodium with isopropyl alcohol and propylene to give a mixture of sodium isopropoxide, allyl sodium, and sodium chloride. Examples 1 and 2 relate to comparative homopolymerizations of butadiene using n-hexane, n-heptane or a C 6 hydrocarbon mixture. Examples 3 and 4 relate to the homopolymerization of butadiene using a mixture of C 4 -C 9 branched hydrocarbons. The catalyst in each case is Na.O.i-C 3 H 7 /CH 2 = CH.CH 2 .Na/NaCl, and the dihydroaromatic hydrocarbon is 1,4-dihydroxy. benzene.
