Abstract:
The present invention relates to a method of using a block copolymer comprising monomeric units of 1,4-butadiene and at least one other comonomer addition products to lower the gel point of crude petroleum, lubricating oils, and petrochemicals. The block copolymer comprises at least 10 % by weight of at least one crystallizable block and at least one low crystallinity block.
Abstract:
The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated and functionalized. The dispersant substances include compositions including a copolymer of two different conjugated dienes, a copolymer of a p-alkylstyrene and a conjugated diene, or a homopolymer of a conjugated diene. The polymers are selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective functionalization. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in their dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.
Abstract:
The invention concerns semi-fluorinated alkanes of the general formulae RFRH and RFRHRF, RF being a linear or branched perfluoroalkyl group and RH being a linear or branched saturated (hydrocarbon)-alkyl group.

Abstract:
The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated and functionalized. The dispersant substances include compositions including a copolymer of a ring substituted styrene and a conjugated diene. The polymers are selectively hydrogenated to produce polymers which have highly controlled residual amounts of aromatic unsaturation, permitting highly selective functionalization. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in their dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.
Abstract:
A particulate, free-flowing and rapid dissolving polymer composition is prepared by comminuting a high molecular weight thermoplastic or viscoelastic polymer (11) at a temperature below its glass transition temperature while maintaining the polymer in an inert environment. A finely divided, solid coating agent (12) is mingled with the comminuted polymer while maintaining the polymer particles in a cold and inert atmosphere. The particles of coating agent are formed into a protective shell (13) around each polymer particle by mixing the components while raising the temperature of the mixture. The polymer composition finds use as a drag reducing agent; as an anti-misting agent; to enhance the efficiency of oil skimming processes and devices; and for the preparation of polymer solutions for other uses.

Abstract:
The effectiveness is prolonged for catalytic oxidizers to reduce emissions of both HC and CO from two-stroke gasoline engines. A compound of a platinum group metal is added to the cylinder of the engine to make it available as an active oxidation catalyst by combustion of the fuel. Preferably, the platinum group metal compound is added with the lubricating oil, but can be added to the fuel or through a separate injection.
Abstract:
Method of reduced temperature metallic vapor phase combustion for jet, turbine, diesel, fuel oil, and gasoline combustion systems. More particularly, it relates to methods and composition of metal-containing fuels comprised of enhanced combustion structure capable of increasing combustion burning velocity and reducing combustion temperature.
