    Publication number: 20150025280
    Abstract: A catalytic system for reductive carbonylation of an alcohol that includes a rhodium complex, an iodide-containing catalyst promoter, and a supporting phosphorus-containing bidentate ligand for the rhodium complex containing at least one aromatic substituent covalently attached to at least one phosphorus of the supporting phosphorus-containing bidentate ligand in an ortho position with an alkoxy substituent or an aryloxy substituent.

  • PROCESS FOR PRODUCING LOW MOLECULAR WEIGHT ETHYLENE- AND ALPHA-OLEFIN-BASED MATERIALS
    Publication number: 20140357918
    Abstract: The present invention generally relates to a process that prepares polyethylenes, poly-?-olefins or poly(co-ethylene-?-olefin) having backbone weight average molecular weights less than 2500 daltons. The process uses a metal-ligand complex as a precatalyst and can be carried out at temperatures ranging from 30° C. to 300° C. The relatively low molecular weight of the products enables improved viscosity control for a wide variety of applications.

  • HYPERBRANCHED OLEFIN OIL-BASED DIELECTRIC FLUID
    Publication number: 20140330056
    Abstract: The present invention generally relates to a dielectric composition which is a poly-?-olefin or poly(co-ethylene-?-ol-efin) having a backbone weight average molecular weight less than 10,000 daltons. The dielectric composition uses a metal-ligand complex as a precatalyst and exhibits a hyperbranched structure that enables low viscosity, and therefore good flow characteristics, combined with high fire point due to ability to increase molecular weight via branching rather than backbone growth. Other desirable properties include lowered pour point due to crystallization disruption, and desirable thermal oxidative stability.
