    摘要： A drag reducing composition comprising particles of at least two different drag reducing polymers. The different drag reducing polymers can be formed by different processes, such as bulk polymerization or emulsion polymerization, and the particles of the different drag reducing polymers can have different mean particle sizes. The drag reducing compositions can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.

    摘要： A modified latex drag reducer and methods of making and using the drag reducer in order to reduce friction losses resulting from turbulent fluid flow through a conduit. Particularly, the modified latex drag reducer is formed from an initial latex which is a product of an emulsion polymerization reaction. The initial latex is then modified, preferably by admixing with at least one low HLB surfactant or at least one solvent, or both, to form a modified latex with an enhanced dissolution rate in a hydrocarbon stream over the initial latex.

    摘要： A polyimide film is described having improved adhesion prepared by coating the surface of a partially cured or partially dried polyamide acid film with an organic solvent solution of a metal salt and heating the coated film to both convert the polyamide acid to polyimide and dry the film. By proper selection of the metal salt either a one-side adherable or two-side adherable polyimide film can be obtained. The polyimide film can be used in electrical insulating and flexible printed circuit applications where superior adhesion is an important requirement.

    摘要： Drag reducing compositions comprising polymer particles, where the polymer particles include copolymers comprising the residues of at least one methacrylate monomer and at least one comonomer having a polymerizable vinyl group, where the comonomer has no more than one pendant substituent per vinyl carbon. The drag reducing compositions can have improved dissolution rates in hydrocarbon-containing fluids. The drag reducing compositions can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.

    摘要： A method of preparing a drag reducing polymer wherein the drag reducing polymer is able to be injected into a pipeline, such that the friction loss associated with the turbulent flow through the pipeline is reduced by suppressing the growth of turbulent eddies. The drag reducing polymer is injected into a pipeline of liquid hydrocarbon hydrocarbon having an asphaltene content of at least 3 weight percent and an API gravity of less than about 26° to thereby produce a treated liquid hydrocarbon wherein the viscosity of the treated liquid hydrocarbon is not less than the viscosity of the liquid hydrocarbon prior to treatment with the drag reducing polymer. The drag reducing polymer has a solubility parameter within 4 MPa1/2 of the solubility parameter of the liquid hydrocarbon. The drag reducing polymer is also added to the liquid hydrocarbon in the range from about 0.1 to about 500 ppmw.
