摘要： 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.

摘要： Chemically reactive liquids such as catalyzed monomers and prepolymers are mixed with finely divided solids to form a homogeneous blend by chilling the liquid to a temperature below its solidification point, forming it into finely divided solidly frozen particulates, chilling the finely divided solids to a temperature below the solidification temperature of the reactive liquid and mixing the materials together without allowing the temperature to rise to the liquid solidification point. The admixture may then be formed into a permanent shape by warming to a temperature whereat the frozen liquid melts and the liquid is caused to react.

摘要： Particles of two different normally solid materials are caused to react by generating free radicals on the surfaces of at least one of the solids by mechanical working, suitably by comminution, at cryogenic temperatures. At least one of the solids is preferably a polymeric material while the other may be a different polymer, a catalyst, a lubricity enhancing material, a filler, a pigment or the like.

摘要： Toxic liquids, especially halogenated aromatic hydrocarbons, are immobilized within a container by dispersing cryogenically comminuted polymer particles in a surface active state throughout the liquid. The polymer is injected into a container holding the toxic liquid as a slurry of particles in a cryogenic refrigerant. Use of a heat, shear or radiation degradable polymer as the immobilizing agent allows the solidified liquid to be returned to a fluid state for later disposal by incineration.

摘要： An ultrahigh molecular weight polymer, such as ultrahigh molecular weight polyisobutylene, is used as an additive to enhance the coating properties of a solvent. The polyisobutylene has a molecular weight of at least 2.5-3.0 million daltons, preferably greater than about 6 daltons, and is provided in a preferred concentration of 0.05 to 0.3%. The solvent can be a medicinal grade mineral oil. Other suitable solvents include hydrocarbon oil and low viscosity, synthetic compositions. In all cases, the coating properties of the solvent are greatly enhanced by the addition of ultrahigh molecular weight polyisobutylene. In another aspect of the invention, ultrahigh molecular weight polyisobutylene is used as an additive to enhance the viscoelasticity of a mineral oil based sunscreen formulation. In still another aspect of the invention, the fibers of a fabric material are coated with an ultrahigh molecular weight polymer to greatly strengthen the fabric. Other applications include improved automobile polishes and paint sealers, rust removers, and leather treatments.

摘要： A dual drum skimmer is provided for the removal and recovery of oil floating on water. The skimmer includes two oil pick-up drums arranged along a common axis which pick up oil and deposit it in a collection trough. Oil deposited in the collection trough is directed to a reservoir trough arranged on the opposite side of the drums from the collection trough. The drums are formed as hollow, closed cylinders and, together with the reservoir trough, provide the total buoyancy necessary to float the skimmer. The skimmer is particularly effective in shallow and in trash laden water and can operate in water depths of as little as three inches.

摘要： Dispersions of oil and similar liquids in water are clarified with separation of the oil and water phases by mixing the dispersion with a polymer dissolved in an oil miscible solvent in a manner such that contact between the polymer solution and dispersed oil droplets is achieved. The polymer must be soluble in the oil and must have a molecular weight sufficiently high to impart viscoelasticity to the resulting solution of polymer in solvent and oil. Thereafter, the oil and water phases are readily separated by settling and decantation, or by enhanced phase separation techniques such as centrifugation.

摘要： High molecular weight, water soluble polymers are dissolved to form liquid solutions at relatively low polymer concentrations and solid, water-plasticized composites at higher polymer concentrations by admixing finely divided polymer particles with ice particles at temperatures below, and preferably far below, the freezing point of water. The admixture is then allowed to warm causing the ice to melt and the polymer to dissolve in the water.
