摘要：Aluminium aminocompounds of the formulae: (CH3)2NAlH2, (iso-C3H7)2NAlH2, (CH3)2NAlHBr, (C6H5)2NAlHCl, (C6H5)2NAlH2, (C2H5)2NAlHCl, (CH3)(C2H5)NAlHI, (C6H5CH2)2NAlHCl, <FORM:0979391/C1/1> and <FORM:0979391/C1/2> are prepared by reacting an aluminium hydride, preferably complexed with an aliphatic amine, with a secondary amine. In the Specification the preparation of the following compounds are described:-(C6H5)2NAlHCl by reacting a benzene solution of AlH2Cl, complexed with an aliphatic amine with a benzene solution of diphenylamine; the last compound listed above by reacting aluminium hydride complexed with an aliphatic amine with piperidine; and (CH3)2 NAlHBr by reacting AlH2BrN(CH3)3 with HN(CH3)2.ALSO:A polymerization catalyst for butadiene comprises (1) a compound of a transition metal, (2) a hydride of the formula <FORM:0979391/C3/1> where X and Y are hydrogen, or halogen atoms, or a group of the formula <FORM:0979391/C3/2> wherein R and R1 are alkyl, aryl, arylalkyl, or cycloalkyl groups, and optionally (3) iodine, an inorganic iodide, or an aluminium hydride as under (2) containing iodine. Compound (2) may be complexed with Lewis bases such as ethers, tetrahydrofurane, or tertiary amines. Compound (1) may be TiCl4, TiI4, TiI2Cl2, cobalt acetylacetonate, or TiCl2(O-iso-C3H7)2. Compound (2) may be AlHCl2. (C2H5)2O, AlHBr2(C2H5)2O, AlH2I. (C2H5)2O, AlHCl2. N(CH3)3, (CH3)2N. AlH2, (iso-C3H7)2NAlH2, (C6H5)2NAlH2, (CH3)2NAlHBr, (C2H5)2 NAlHCl, (CH3) (C2H5)NAlHI, (C6H5CH2)2 NAlHCl, (CH3)4N2Al-H, or <FORM:0979391/C3/3> The inorganic iodide may be boron, lithium, aluminium, magnesium, or cobalt. The polymerization of butadiene is effected by conventional techniques e.g. in inert hydrocarbon diluents and solvents, and termination of the polymerization by addition of methyl alcohol containing an antioxidant. The polymer has a high cis-1, 4 configuration.
