    Abstract: The invention comprises anthraquinone dyes of the formula wherein R1 represents a 1,3-propylene radical which may be substituted, R2 represents a C4-C12 alkyl radical, and n represents 0 or 1 and the second -NHR1-O-R2 radical which may be present is in 4- or 5-position of the anthraquinone nucleus. They may be obtained by reacting 1-chloro-, or a 1-nitro-, 1,4-dichloro- or 1,5-dinitro-anthraquinone with an amine of the formula H2N-R1-O-R2 or by reacting 1,4-dihydroxyanthraquinone in the presence of reducing agents or the leuco compounds of 1,4-dihydroxyanthraquinone or of 1,4-diaminoanthraquinone or mixtures of both with amines of the above formula and oxidizing the leuco compound so obtained to the anthraquinone dye. Specified amines of the above formula are 3-butoxypropylamine, 3-decyloxypropylamine, 3 - dodecyloxypropylamine and 3 - (2 - ethylhexoxy) - propylamine. Examples are given for the production of the dyes. The dyes are used for colouring petroleum products, e.g. gasoline, either alone or together with other known dyes.

    Abstract: Olefins (e.g. ethylene and styrene) may be polymerized using as a catalyst a compound of a metal of Group IVb, Vb and VIb (Deming) together with a 3,3-dialkylpentylene-1,5-aluminium compound of formula wherein R1 is C1-C4 alkyl, R2 is C2-C4 alkyl, R3 is hydrogen or C2-C4 alkyl and n is 1 or an integer greater than 1 (see particularly Example 6).ALSO:The invention comprises 3,3-dialkylpentylene-1,5-aluminium compounds of formula: where R1 is C1-C4 alkyl, R2 is C2-C4 alkyl, R3 is hydrogen or C2-C4 alkyl, and n is 1 or an integer greater than 1. They may be prepared by reacting a diolefine of formula wherein R1 is C1-C4 alkyl with an organo aluminium compound of formula Al(R2)2R3 where R2 is C2-C4 alkyl and R3 is hydrogen or C2-C4 alkyl. The reaction may be carried out at temperatures between 20 DEG and 160 DEG C., with or without a solvent and at normal, increased or reduced pressure. Solvents specified include benzene, toluene, ethylbenzene, the xylenes, heptane, octane and decane. The products may be used together with compounds of metals of Group IVb, Vb and VIb (Deming) as catalysts for the polymerisation of olefines (see Group IV(a)).

    Abstract: Isotactic polystyrene is made by polymerizing styrene in the presence of a catalyst comprising an organometallic compound of the metals aluminium, zinc, or magnesium, and a transition metal compound, and in the presence of an aromatic diluent of boiling point between 80 DEG C. and 220 DEG C., which contains at least one liquid aliphatic and/or cycloaliphatic hydrocarbon and which is added during polymerization. In the preferred embodiment, the styrene is first polymerized in the aromatic diluent, and when the reaction mixture has a viscosity of between 10 and 100 poises, the aliphatic and/or cycloaliphatic hydrocarbon is added. Suitable catalysts are described in Specifications 810,023, and 810,024. Specified aromatic solvents are benzene, tetrahydronaphthalene, toluene, xylene, ethylbenzene, and chlorobenzene. The added hydrocarbon may be hexane, cyclohexane, heptane, octane, or gasoline.
