    摘要： Size-selective hemocompatible porous polymeric adsorbents are provided with a pore structure capable of excluding molecules larger than 50,000 Daltons, but with a pore system that allows good ingress and egress of molecules smaller than 35,000 Daltons. The pore system in these porous polymeric adsorbents is controlled by the method of synthesis so that 98% of the total pore volume is located in pores smaller than 300 Angstroms (Å) in diameter with a working pore size range within 100 to 300 Å in diameter. The porous polymeric adsorbents of this invention are very selective for extracting midsize proteins, such as cytokines and β2-microglobulin, from blood and other physiologic fluids while keeping the components required for good health such as cells, platelets, albumin, hemoglobin, fibrinogen, and other serum proteins intact.

    摘要： A color change paint and varnish removal formulation is provided. The formulation comprises: at least one penetrant, at least one water insoluble carrier and at least one color visible colorant whereby the formulation is applied to the target area and as the surface of the formulation dries, the penetrant migrates away from the dehydrating surface and a surface crust of beads is formed; the beads have a particle size that allows the scattering of visible light into white light and produces the whitening and dilution of the visible color and thus, there is a color change to indicate that the stripping action of the formulation has ceased and is ready for the scraping and removal step.

    摘要： Thermoset polymer particles are used in many applications requiring lightweight particles possessing high stiffness, strength, temperature resistance, and/or resistance to aggressive environments. The present invention relates to the use of two different methods, either each by itself or in combination, to enhance the stiffness, strength, maximum possible use temperature, and environmental resistance of such particles. One method is the application of post-polymerization process steps (and especially heat treatment) to advance the curing reaction and to thus obtain a more densely crosslinked polymer network. In general, its main benefits are the enhancement of the maximum possible use temperature and the environmental resistance. The other method is the incorporation of nanofillers, resulting in a heterogenous “nanocomposite” morphology. In general, its main benefits are increased stiffness and strength. Nanofiller incorporation and post-polymerization heat treatment can also be combined to obtain the benefits of both methods simultaneously. The present invention relates to the development of thermoset nanocomposite particles. It also relates to the optional further improvement of the heat resistance and environmental resistance of such particles via post-polymerization heat treatment. Furthermore, it also relates to processes for the manufacture of said particles. Finally, it also relates to the use of said particles in the construction, drilling, completion and/or fracture stimulation of oil and natural gas wells; for example, as a proppant partial monolayer, a proppant pack, an integral component of a gravel pack completion, a ball bearing, a solid lubricant, a drilling mud constituent, and/or a cement additive.

    摘要： A color change paint and varnish removal formulation is provided. The formulation comprises: at least one penetrant, at least one water insoluble carrier, at least one color visible colorant, at least one thickening agent, at least one wetting agent, and at least one activator, whereby the formulation is applied to the target area and as the surface of the formulation dries, the penetrant migrates away from the dehydrating surface and a surface crust of beads is formed; the beads have a particle size that allows the scattering of visible light into white light and produces the whitening and dilution of the visible color and thus, there is a color change to indicate that the stripping action of the formulation has ceased and is ready for the scraping and removal step.
