  • Patent number: 7999022
    Abstract: Polymer slurries of ultrahigh molecular weight polyalpha-olefins are made stable toward settling, separation and agglomeration by surface treatment with a combination of wax and optional relatively high-density particulates. The selection of the surface coating acts not only as an anti-blocking agent, or partitioning aid to keep the tacky polymer particles separated, but also provides the suspended polymer particle with a density that matches the carrier. This prevents separation of the slurry components over time. Such materials, ultimately used as pipeline additives to reduce the fluid drag and increase the volumetric throughput, can be stored and shipped for extended periods of time without degradation of the slurry quality. Upon injection into the pipeline, the polymer particle dissolves quickly, unhindered by the coating.

  • Patent number: 6503976
    Abstract: A coating composition for fabrics includes wetted microspheres containing a phase change material dispersed throughout a polymer binder, a surfactant, a dispersant, an antifoam agent and a thickener. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. To prepare the coating composition, microspheres containing phase change material are wetted and dispersed in a dispersion in a water solution containing a surfactant, a dispersant, an antifoam agent and a polymer mixture. The coating is then applied to a fabric.

  • Patent number: 6444738
    Abstract: Emulsions containing a hydrocarbon liquid in a continuous phase and alcohol and/or water in a dispersed phase. The emulsions are stabilized by an emulsifier and a coupling agent. The emulsifier is a copolymer containing at least one relatively hydrophobic polymeric block of styrene or ring substituted styrene monomer, and at least one relatively hydrophilic polymeric block of at least one monomer, such as ethylene oxide, selected from the group having the formula H(O—R)nOH where R is an aliphatic radical containing from 1 to 4 carbon atoms and n is a number between 20 and 300. The coupling agent is a copolymer containing at least one polymeric block of styrene or ring substituted styrene monomer, and at least one block being of a saturated or unsaturated aliphatic hydrocarbon moiety, such as butadiene. In order to stabilize the emulsion against stratification or breakage under heat soak conditions the coupling agent contains the styrene monomer and the hydrocarbon moiety in a weight ratio of from 1:0.

  • Patent number: 6403686
    Abstract: Improved compositions of the present invention are made from a rubber latex component (A) and an oil carrier component (B) having hygroscopic and vulcanizing agents. Upon intermixing of the components A and B, an elastomeric composition is formed that can undergo a rheological transformation from a flowable liquid to a solidified elastomeric solid. An improved linear slope between fluidity and temperature is achieved by using naphthenic oil in the oil carrier component (B) with an organic rheology modifier, such as a modified castor oil and/or a polyamide. Further exemplary compositions comprise an inorganic rheology modifier such as an activated clay.

  • Patent number: 6287405
    Abstract: There is disclosed a method and composition for cosmetically repairing a surface void in polyolefin objects. The method involves inserting a repair composition into the void and then applying heat thereto to fuse the repair composition with a surrounding portion of the polyolefin object. The repair composition is a physical mixture of a thermoplastic powder, a resin binder, and a solvent, having a paste-like consistency. The repair composition may be neutral in color, or may contain a colorant to closely match the underlying object. The heating step can be performed with an open flame or with a heat gun.
