    Abstract: The frictional pressure drop, or drag, of hydrocarbon fluids flowing through pipelines of various lengths is preferentially lowered by dissolving therein polymeric drag reducer suspensions exhibiting bi- or multimodal particle size distributions. Drag reducers having larger particle sizes dissolve more slowly than drag reducers having smaller particle sizes, and vice versa. By using at least bi-modal particle size distributions, the drag reduction effect may be distributed more uniformly over the length of the pipeline where smaller sized particles dissolve sooner after injection (upstream in the pipeline), and larger sized particles dissolve later (further along the pipeline). Drag reducer suspensions with bi- or multimodal particle size distributions may be made by suspension polymerization.

    Abstract: A particulate, free-flowing and rapid dissolving polymer composition is prepared by comminuting a high molecular weight thermoplastic or viscoelastic polymer at a temperature below its glass transition temperature while maintaining the polymer in an inert environment. A finely divided, solid coating agent is mingled with the comminuted polymer while maintaining the polymer particles in a cold and inert atmosphere. The particles of coating agent form a protective shell around each polymer particle by tumble 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: A method for separating liquids, particularly hydrocarbons from water, whereby a small amount of a high molecular weight polymer is dissolved in the hydrocarbon to render it viscoelastic. A hydrocarbon layer is then mechanically removed from the water in a manner which causes rapid stretching of the hydrocarbon with attendant development of elastic properties in the hydrocarbon layer. The polymer may be applied to the surface of the hydrocarbon as droplets of a relatively concentrated polymer solution or as solid particulates having a polymer core covered by a powdered solid material which is non-reactive toward the polymer.
