    Abstract: 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.

    Abstract: 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.

    Abstract: A dielectric fluid composition for electrical apparatus comprises a functionalized methyl-12-carboxy methyl stearate having desirable properties including a pour point less than −30° C. and a fire point greater than 250° C. It may be prepared by a process wherein methyl-12-hydroxy methyl stearate is transesterified by reaction with a C3-C20 alcohol to form the hydroxy methyl ester, followed by reaction with a linear or branched C4-C20 carboxylic acid selected from free acid chlorides, fatty acids, carboxylic acid anhydrides, and combinations thereof. The second step serves to end-cap the hydroxyl groups, thereby producing the functionalized methyl-12-carboxy methyl stearate compound that exhibits improved thermoxidative stability and low temperature flowability, as well as increased fire point.
