Such derivatives are selected from the group consisting of(a) esters of aromatic, aliphatic or cycloaliphatic acids having at least 2 carbon atoms and 1, 2 or 3 carboxyl groups;(b) urethanes of aromatic, aliphatic or cycloaliphatic isocyanates;(c) monoethers of polyalkylene oxide glycols having 2 to 50 alkylene oxide units each containing 2 or 3 carbon atoms and the alkylpolyoxyalkylene sulfates derived therefrom;(d) sulfates.The branched-chain monoalcohols are obtained by reduction of branched-chain monocarboxylic acids or esters thereof. Said acids are telomeric acids obtained by the free radical addition of 1 mole of acetic anhydride to at least three moles of hexene and/or higher olefins containing up to 30 or more carbon atoms (C.sub.30+) in the presence of a trivalent manganese compound. The products of this invention are suitable for use in engine lubricating oils, lubricant compositions for polymers and wax compositions.Type: GrantFiled: October 26, 1979Date of Patent: April 6, 1982Assignee: Akzona IncorporatedInventors: Jacobus J. Zeilstra, Willem J. de Klein, Joannes D. Bik

Patent number: RE31874Abstract: Propagation of electrical trees and water trees in electrical insulation made of ethylene homopolymers or copolymers with an unsaturated monomer is inhibited by the addition to the insulating composition of an organic carboxylic ester having at least one aromatic ring and at least three carboxylic ester groups, the ester being liquid at the operating temperature of the electrical equipment in which the insulation is used. The main utility of the inhibitors of this invention is in the primary insulation for power transmission cables, especially those used in high voltage applications.Type: GrantFiled: November 2, 1983Date of Patent: April 30, 1985Assignee: E. I. Du Pont de Nemours and CompanyInventors: John K. Beasley, Edward J. Urban
