Abstract: The present disclosure is directed to a dielectric fluid comprising a farnesene-based oligomer and an antioxidant and devices containing the dielectric fluid.

Abstract: The present disclosure provides a dielectric fluid composed of a genetically engineered microbial oil (GEMO) and an antioxidant. The GEMO includes a triglyceride and an amount of small glyceride. The amount of small glyceride is within a range from 0.1 wt % to 30 wt %, based upon the GEMO weight.

Abstract: Flexible cable comprises a crosslinked insulation sheath made from a composition comprising in weight percent based on the weight of the composition; (A) 60-95% of an ethylene polymer of crystallinity of less than 40%; (B) 4 to less than 40% of a propylene polymer with an upper melting point of greater than or equal to (>)130° C.; and (C) >0.5% peroxide; with the proviso that the ethylene polymer either comprises a continuous matrix within which the propylene polymer is dispersed or is co-continuous with the propylene polymer. Compatibilizers are optional to the composition.

Abstract: Plasticizers are made from oil with a narrowed, fatty acid polydispersity and extracted from a microorganism, such as a natural or genetically modified bacterium or algae. These plasticizers can comprise either a large content of either saturated C4 and/or C6 triglycerides or unsaturated C12 or greater triglycerides that have been chemically modified by one or more of epoxidation, acylation and esterification. The plasticizers of this invention are particularly well-suited for use with polar polymeric resins such as PVC.

Abstract: Epoxidized fatty acid alkyl esters produced, at least in part, from a natural-oil soap stock and methods for making such epoxidized fatty acid alkyl esters. Epoxidized fatty acid alkyl esters can be employed in plasticizer compositions in combination with at least one epoxidized natural oil. Such plasticizers can be employed in preparing polymeric compositions comprising a polymeric resin, such as polyvinyl chloride, and the plasticizer. Such polymeric compositions can, in turn, be employed in making various articles of manufacture, such as coatings or jackets for wires and cables.

Abstract: Addition polymers of ethylenically unsaturated monomers are provided comprising a 5-, 6- or 7-membered polymer unit formed from a copolymerizable, unsaturated, chain transfer agent containing a labile hydrogen and capable of forming by means of a hydrogen shift mechanism a free radical having 5, 6 or 7 atoms between and including the .alpha.-carbon of the ethylenically unsaturated group and the labile hydrogen.

Abstract: Optically isotropic blends comprising styrene/acrylonitrile copolymers containing from 18 to 32 percent acrylonitrile and methyl methacrylate/glutarimide resins containing from 10 to 50 weight percent methyl methacrylate and having stress optical coefficient of between -500 Brewsters and +500 Brewsters are usefully employed in the preparation of molded objects having reduced birefringence.

Abstract: Intrinsically low birefringent molding polymers having a molten stress optic coefficient that is greater than or equal to -1000 Brewsters and less than or equal to +1000 Brewsters, a glass transition temperature of at least 140.degree. C., and a water absorption (A.sub.H.sbsb.2.sub.O) according to ASTM D570-81 after 24 hours immersion in water at 23.degree. C. of less than 0.25 percent comprising in polymerized form at least one structural component providing a positive melt homopolymer stress optic coefficient and at least one other structural component providing a negative melt homopolymer stress optic coefficient.

Abstract: A process for preparing glutarimide resins by the amidization and cycloimidization of methacrylate resins in the presence of a solvent characterized in that the solvent consists essentially of cyclohexanol.

Abstract: Resins comprising methacrylimide functionality and C.sub.2-20 alkyl or cycloalkyl methacrylate functionality are prepared by amidization and imidization of corresponding prepolymers comprising C.sub.2-20 alkyl or cycloalkyl methacrylate functionality and methyl methacrylate.

Abstract: A process for hydrogenating phenylacetylene in the presence of an excess of styrene by contacting a mixture of hydrogen and the phenylacetylene with a catalyst obtained by the reduction of a copper compound on a support.
