Abstract: The present invention relates to a novel proton-conducting polymer membrane based on polyazole block polymers which, owing to their outstanding chemical and thermal properties, can be used widely and are suitable in particular as polymer electrolyte membrane (PEM) for producing membrane electrode units or so-called PEM fuel cells.

Abstract: A lubricant composition having improved non-Newtonian viscometrics includes at least 85 weight percent of a base oil and 1 to 15 weight percent of a lubricant additive. The additive itself includes 10 to 80 weight percent of a diluent oil and 30 to 80 weight percent of a random co-polymeric viscosity index improver. The viscosity index improver is the free-radical polymerization product of at least 5 to 15 weight percent methyl methacrylate and 5 to 95 weight percent of a C8-C10 alkyl (meth)acrylate. The additive is formed using a method that includes the step of providing the diluent oil, the methyl methacrylate, the C8-C10 alkyl (meth)acrylate, and a free-radical initiator. The method also includes the steps of flowing the diluent oil into a reactor, flowing the methyl methacrylate and the C8-C10 alkyl (meth)acrylate into the reactor independently from the free-radical initiator, and flowing the free-radical initiator into the reactor.

Abstract: Poly methacrylate copolymers are disclosed which comprising from about 60 to about 96 weight percent of a C12-C16 alkyl methacrylate and from about 40 to about 4 weight percent of a C18-C30 alkyl methacrylate and provide excellent low temperature properties to lubricating oils.

Abstract: The instant invention provides a lubricant composition having improved four-ball antiwear properties. The lubricant composition includes a base oil and one or more alkylethercarboxylic acid corrosion inhibitor(s) having the formula: wherein R is a straight or branched chain C6-C18 alkyl group and n is a number of from 0 to 5. The lubricant composition also includes an ashless antiwear additive including phosphorous. The four-ball antiwear properties are reported as an average diameter of wear scars pursuant to ASTM D4172. The average diameter of the wear scars resulting from the lubricant composition are at least 5% smaller than the average diameter of the wear scars resulting from a standard that includes the base oil and the antiwear additive and that is free of the one or more alkylethercarboxylic acid corrosion inhibitor(s).

Abstract: A galvanic ground isolator adapter protects against galvanic corrosion on a boat when a boat power system is connected to a shore power system. A ground isolation assembly in the ground connection between the two system grounds prevents current from passing between the two system grounds when the voltage difference between the two is low. When the voltage difference exceeds a preset value, the ground connection is established. The adapter is entirely contained within a rigid housing with a male plug at one end and a female socket at the other end. In this form it can be simply connected to a power cord that is normally used in connecting the shore and boat power systems. It may be provided with a locking mechanism that prevents it being removed once it is attached. It may be supplied with a sonic alarm to indicate when current is flowing in the ground connection.

Abstract: The present invention is directed to the use of alkyl (meth)acrylate polymers or copolymers of the formula (I) In-Poly-(E)y??(I) as cold flow improvers in biodiesel fuel (or bio-fuel) and biodiesel compositions incorporating said polymers or copolymers, obtained by nitroxyl mediated controlled free radical polymerization, wherein In is the initiator fragment starting the polymerization reaction; E is an end group bearing at least one stable free nitroxyl radical, which is bound via an oxygen atom to the polymer or copolymer; or a group which results from a substitution or elimination reaction of the attached stable free nitroxyl radical; Poly is any polymer or copolymer formed from ethylenically unsaturated monomer(s); and y is a number 1 or greater than 1 indicating the average number of end groups E attached to Poly.

Abstract: Disclosed are stabilized biodiesel fuel compositions, which compositions comprise a biodiesel fuel, for example the methyl esters of the fatty acids of rapeseed or soy oil, which compositions comprise a biodiesel fuel and an effective stabilizing amount of a combination of i) one or more compounds selected from the group consisting of the sterically hindered phenolic antioxidants and ii) one or more compounds selected from the group consisting of the triazole metal deactivators.
