    Abstract: Production of organometallic compounds of sodium and potassium with alkylaromatic hydrocarbons (X) by reaction of the metal with a monochloride of a hydrocarbon (Y) and reaction of the organometallic compound formed with the alkylaromatic hydrocarbon (X). A fine dispersion of the metal in the alkylaromatic hydrocarbon (X) is first prepared by stirring a mixture of molten metal and hydrocarbon (X) in the presence of a dispersing agent; then the monochloride of the hydrocarbon (Y) is slowly added. The sodium or potassium compounds may be used for organometallic reactions or as monofunctional polymerization catalysts.

    Abstract: Mixtures of polystyrene and a block copolymer of a monovinyl-aromatic compound and a conjugated diene. The mixture contains a thermoplastic, non-elastomeric block copolymer having a star-shaped branched structure, the branches being of at least two types of different average composition, and at least 50% by weight of the monovinyl-aromatic compound being present as terminal polymer blocks in one or more of the branches. The mixtures, which exhibit good transparency and high impact strength, are particularly suitable for the manufacture of moldings and packaging materials.
