    摘要: A process to prepare a relatively inexpensive utility fluid comprises contacting together ethylene and a coordination-insertion catalyst and, optionally, an alpha-olefin, in a continuously-fed backmixed reactor zone under conditions such that a mixture of a hyperbranched oligomer and a branched oligomer is formed. The hyperbranched oligomer has an average of at least 1.5 methine carbons per oligomer molecule, and at least 40 methine carbons per one-thousand total carbons, and at least 40 percent of the methine carbons is derived from the ethylene, and the average number of carbons per molecule is from 25 to 100, and at least 25 percent of the hyperbranched oligomer molecules has a vinyl group and can be separated from the branched oligomer, which has an average number of carbons per molecule of up to 20. The coordination-insertion catalyst is characterized as having an ethylene/octene reactivity ratio up to 20 and a kinetic chain length up to 20 monomer units.

    摘要: The present invention generally relates to a process that prepares polyethylenes, poly-α-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.

    摘要: The present invention generally relates to a dielectric composition which is a poly-α-olefin or poly(co-ethylene-α-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.
