    摘要： This invention provides for an aqueous metallic flake containing coating composition having improved glamour. The coating composition includes a neutralized phosphated segmented copolymer dispersed in an aqueous carrier. The phosphorous moiety in the segmented copolymer passivates the metallic flakes, such as aluminum flakes, used to produce the glamour. As a result, generation of hydrogen gas is substantially reduced. The segmented copolymer is provided with hydrophobic and nonionic hydrophilic segments. Applicants have discovered that by including a nonionic hydrophilic segment in the segmented copolymer, glamour of the resultant coating composition can be improved. Furthermore, by controlling the molar ratio of the hydrophobic segment to the hydrophilic segment in the segmented copolymer and the solubility parameter of the hydrophobic segment, applicants have discovered that it is possible to use either a non-passivated aluminum flake or pre-passivated aluminum flake in the coating composition while improving glamour over conventional metallic paints and still maintaining the dispersion stability of the composition. As a result, formulator has substantial leeway in selecting from a wide array of environmentally acceptable solvents, film forming binders and components, which are typically added to a coating composition for improving the coating properties. The composition is most suited for use in automotive OEM and refinish metallic paints.

    摘要： A process for preparing 1,2-diimine compounds of the formula I where R1 and R2 are, independently of one another, alkyl, aryl or metallocenyl radicals, and R3, R4 are, independently of one another, H, alkyl or aryl radicals or R3 and R4 are joined so as to form, with inclusion of the two imine carbon atoms, a 5- to 8-membered ring which may be saturated or unsaturated and may be unsubstituted or substituted by any hydrocarbon radicals. The process involves reacting 1,2-dicarbonyl compounds with primary amines, which have been activated with trialkylaluminum compounds prior to the reaction with the 1,2-dicarbonyl compounds. 1,2-Diimine compounds of the formula I in which R1 and R2 are, independently of one another, metallocenyl radicals can be used to prepare metal complexes which can be used as catalysts in a process for the polymerization of unsaturated compounds.

    摘要： Polyolefins, especially branched polyethylenes, can be made by combining a catalyst that can oligomerize ethylene to one or more alpha-olefins and a polymerization catalyst which can copolymerize ethylene and &agr;-olefins, by first carrying out the process in, for example, a continuous stirred tank reactor or its equivalent, and then in a plug flow reactor or its equivalent. The process minimizes the occurrence of (unreacted) &agr;-olefins in the final polymer product.

    摘要： A catalyst composition that is the combination of or the reaction product of ingredients including an iron-containing compound, a hydrogen phosphite, and a mixture of two or more organoaluminum compounds. This catalyst composition is particularly useful for polymerizing conjugated dienes. When this catalyst composition is used to polymerize 1,3-butadiene into syndiotactic 1,2-polybutadiene the ratio of the organoaluminum compounds can be adjusted to vary the melting temperature and molecular weight of the polymer product.
