Patent number: 9793027Abstract: A dielectric fluid composition for electrical apparatus comprises a functionalized 12-hydroxy stearic acid 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 12-hydroxy methyl stearate is transesterified by reaction with a C3-C20 alcohol to form an alkyl-12-hydroxy stearate, followed by esterification thereof with a linear or branched C4-C20 carboxylic acid. This acid may be a free acid chloride, a fatty acid, a carboxylic acid anhydride, or combination thereof. The resulting functionalized 12-hydroxy stearic acid exhibits improved thermoxidative capability, low temperature flowability, and increased fire point.Type: GrantFiled: May 17, 2016Date of Patent: October 17, 2017Assignee: Dow Global Technologies LLCInventors: Suh Joon Han, Dirk B.

Patent number: 9643900Abstract: 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.Type: GrantFiled: June 24, 2014Date of Patent: May 9, 2017Assignee: DOW GLOBAL TECHNOLOGIES LLCInventors: Daniel J.

Patent number: 9601231Abstract: The present invention generally relates to a dielectric composition which is a poly-?-olefin or poly(co-ethylene-?-olefin) 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.Type: GrantFiled: November 28, 2012Date of Patent: March 21, 2017Assignee: Dow Global Technologies LLCInventors: Jerzy Klosin, Zenon Lysenko, Suh Joon Han
