    摘要： The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated, functionalized, optionally modified and post treated. The dispersant substances include a copolymer of two different conjugated dienes. The polymers are selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective funtionalization. The polymers may be functionalized by hydroformylation followed by reductive amination. 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.

    摘要： The present invention relates to methods for obtaining viral proteins. In particular, the present invention relates to the purification of viral proteins, in particular, of viral membrane proteins from host cells or genetically engineered cells expressing viral proteins, in particular, viral membrane proteins. Specifically, the present invention provides new methods wherein the host cells expressing viral membrane proteins recombinantly or host cells infected with virus and propagating the same are treated with surfactants for membrane solubilization of said host cells.
