  • Patent number: 8362220
    Abstract: The present invention provides compositions of matter useful as deposition agents for making structures, including thin film structures and hard coatings, on substrates and features of substrates. In an embodiment, for example, the present invention provides metal complexes having one or more diboranamide or diboranaphosphide ligands that are useful as chemical vapor deposition (CVD) and/or atomic layer deposition (ALD) precusors for making thin film structures and coatings. Metal complex CVD precursors are provided that possess volitilities sufficiently high so as to provide dense, smooth and homogenous thin films and coatings.

  • Patent number: 8338557
    Abstract: Olefin polymer with narrow molecular weight distribution and specific molecular weight, olefin polymer having functional group introduced at terminal, tapered polymer containing segment wherein monomer composition continuously changes in the polymer chain, olefin polymer having different segments bonded to each other, and process for preparing these polymers. The olefin polymers are polymers of C2-20 carbon atom olefins and have a number-average molecular weight of ?500 and Mw/Mn of ?1.5. In syntheses, an olefin of 2-20 carbon atoms is polymerized in the presence of a catalyst comprising a transition metal compound represented by the formula LmMXn wherein M is a transition metal atom of Group 3-11, m is 1-5, n is a number satisfying a valence of M, L is a ligand—coordinated to the central metal M—which contains a heteroatom having no direct bond to the central metal, and X is e.g. halogen or a hydrocarbon.

  • Patent number: 8324337
    Abstract: A catalyst, co-catalyst, and/or chain transfer agent is added at a time after initiation of an addition polymerization reaction to produce a polymer product with a widened molecular weight distribution relative to having all of the components in the original reaction mixture. The catalyst, co-catalyst, or chain transfer agent may be added discretely or continuously to the reaction to produce a product with a bimodal, trimodal, or other broadened molecular weight distribution.
