The present invention provides multi-armed high MW polymers containing hydrophilic groups conjugated to Factor VIII, and methods of preparing such polymers.

Factor VIII zwitterionic polymer conjugates

This invention relates to a process for producing a product stream with improved reduction of Conradson Carbon Residue ('CCR') and a reduced average boiling point from a heavy hydrocarbon feedstream utilizing a high-pressure, low-energy separation process. The invention may be utilized to reduce the CCR content and reduce the average boiling point in heavy hydrocarbon feedstreams, such as whole crudes, topped crudes, synthetic crude blends, shale oils, bitumen, oil from tar sands, atmospheric resids, vacuum resids, or other heavy hydrocarbon streams. This invention also results in a process with an improved CCR separation efficiency while maintaining permeate flux rates.

The invention relates to liquid chromatography techniques for rapidly characterizing samples, such as polymer solutions, emulsions and dispersions, and to devices for implementing such techniques. The system includes a design that provides the ability to perform chromatographic separations by using mobile phase composition gradients and temperature gradients during separations. The invention accomplishes this by providing mixing zones for a plurality of fluids as well as heated and chilled feeds feeding the fluids to the mixing zones. Additionally, the system provides the ability to analyze separated components with a detector and/or collect separated fractions into vessels of a fraction collector for further separation and/or analysis.

Method for preparing a mixed powder sample by mixing two or more different powders comprising transferring a quantity of a first powder to a mixing vessel and transferring a quantity of a second powder to the mixing vessel to form a powder bed in the mixing vessel comprising the first and second powders. The quantities of the powders are selected so the mixed sample has a predetermined ratio of first powder to second powder. The powder bed is fluidized to mix the powders and produce a mixed sample. The mixed sample weighs about 5 grams or less. The invention also includes apparatus for preparing mixed powder samples by mixing two or more different powders.
