    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.

    Abstract: 16 A mixture of unlike particulate solids is dispersed in liquid nitrogen to form a slurry. The slurry is then subjected to shear and impact forces of sufficient intensity and duration to break up agglomerates, to comminute at least the larger particles, and to obtain a randomly mixed homogeneous suspension. The suspension is thereafter stabilized by removal of liquid nitrogen to form a paste or powder which may be further processed into shapes by extrusion or molding. One preferred embodiment utilizes a batch-to-continuous process for the compounding of rubber with carbon black and other additives.
