    Abstract: A particulate, free-flowing and rapid dissolving polymer composition is prepared by comminuting a high molecular weight thermoplastic or viscoelastic polymer (11) at a temperature below its glass transition temperature while maintaining the polymer in an inert environment. A finely divided, solid coating agent (12) is mingled with the comminuted polymer while maintaining the polymer particles in a cold and inert atmosphere. The particles of coating agent are formed into a protective shell (13) around each polymer particle by 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 translation: 通过在低于其玻璃化转变温度的温度下粉碎高分子量热塑性或粘弹性聚合物（11），同时将聚合物保持在惰性环境中，制备粒状，自由流动且快速溶解的聚合物组合物。 细碎的固体涂层剂（12）与粉碎的聚合物混合，同时将聚合物颗粒保持在冷的和惰性的气氛中。 通过在升高混合物温度的同时混合组分，涂层剂颗粒在每个聚合物颗粒周围形成保护壳（13）。 该聚合物组合物可用作减阻剂; 作为防雾剂; 提高撇油工艺和设备的效率; 并用于其他用途的聚合物溶液的制备。

    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.
