Abstract: The present invention relates to a molybdenum precursor compound, a composition for forming a molybdenum-containing film comprising same, a molybdenum-containing film formed by using same, and a method for depositing the molybdenum-containing film. The molybdenum precursor compound has a single structure and high purity, and thus can form a high-quality molybdenum-containing film, and has excellent thermal stability and low specific resistance, and thus may have various applications in the semiconductor field. In particular, since the molybdenum precursor compound can form a film having excellent coating properties and uniformity even on a substrate having patterns (grooves) on the surface, a porous substrate, a plastic substrate, or a substrate having a complex shape, a high-quality molybdenum-containing film can be easily realized.

Abstract: A catalytic system based on at least one metallocene and on a diorganomagnesium compound of formula RB—Mg—RA is provided, RB being different from RA and comprising a benzene nucleus substituted with a magnesium atom, one of the carbon atoms of the benzene nucleus ortho to the magnesium being substituted with a methyl, an ethyl, an isopropyl or forming a ring with the carbon atom which is its closest neighbour and which is meta to the magnesium, the other carbon atom of the benzene nucleus ortho to the magnesium being substituted with a methyl, an ethyl or an isopropyl, RA being an alkyl, a cycloalkyl or a benzyl, which may be substituted or unsubstituted. The catalytic system makes it possible to increase the functional group content in the synthesis of a functional polymer.

Abstract: A rubber composition for a golf ball core includes (a) a conjugated diene polymer, (b) a multi-component copolymer having conjugated diene units, non-conjugated olefin units and aromatic vinyl units, and (c) an organic peroxide. The conjugated diene units include butadiene units, the non-conjugated olefin units include ethylene units, and the aromatic vinyl units include styrene units. The content of conjugated diene units with respect to the multi-component copolymer is at least 5 wt %. Golf balls having at least one core layer formed of such a rubber composition and a cover of one or more layers encasing the core exhibit improved durability to cracking on repeated impact while maintaining the basic properties required of golf balls, such as flight and spin controllability on approach shots.

Abstract: Provided in this disclosure are zirconium and hafnium complexes that contain 1) a cyclopentadienyl ligand; 2) an adamantyl-phosphinimine ligand; and 3) at least one other ligand. The use of such a complex, in combination with an activator, as an olefin polymerization catalyst is demonstrated. The catalysts are effective for the copolymerization of ethylene with an alpha olefin (such as 1-butene, 1-hexene, or 1-octene).
