  • Patent number: 6558705
    Abstract: Parent disclosure, now U.S. Pat. No. 6,303,133 B1, taught a calcium hydroxide containing evaporation retardant having particles that mutually repel one another because of water-induced ionization. Calcium hydroxide makes the retardant unsuitable for treating overly alkaline agricultural soil, and to substitute plain calcium sulfate for calcium hydroxide would degrade the particle repulsion effect. Substitutable acidified gypsum is made by absorbing about 5 milliliters sulfuric acid per 300 grams calcium sulfate. Blending unemulsified detergent range alcohol in a parts by weight ratio of about one-to-ten with the acidified gypsum produces a soil treatment product for suppressing evaporation of water from treated soil without impairing water infiltration into the same soil.

    Abstract: The invention pertains to enhancing the dispersion on the surface of a still or moving body of a polar liquid, such as water, of particles of a powder of the composition essentially comprising a monolayer-forming constituent, such as hexadecanol or octadecanol or a blend thereof, together with a high proportion of a soluble or sparingly soluble alkaline earth metal hydroxide, more particularly about five times the monolayer-forming constituent's weight when the hydroxide constituent is—as preferred for potable water evaporation reduction—calcium hydroxide procured as inexpensive pre-powdered agricultural hydrated lime. A melt-processing manner of producing the composition is described. When particles of the composition contact the body of water, so long as lime remains present in any floating particles, they will be individually positively charged, resulting in their repulsion from one another. This enhanced dispersal effect is due to the ionization of the calcium hydroxide.

  • Publication number: 20010009942
    Abstract: A suspending agent-containing slurry is disclosed which comprises a dispersant and a particulate suspending agent having a particle size distribution in which the particle diameter at weight-cumulative 95%, from the minimum particle size, is 1 &mgr;m or smaller. A method for efficiently producing the suspending agent-containing slurry is also disclosed. A process for suspension polymerization by use of the suspending agent-containing slurry is further disclosed. The slurry not only has such an excellent suspending ability in suspension polymerization that it enables the production of vinyl polymer beads having a narrow bead size distribution, but also is capable of retaining this ability over long and of exhibiting the same ability even when it has a high concentration. The suspension polymerization process enables vinyl polymer beads having a narrow bead size distribution to be produced efficiently due to the use of the slurry.

  • Patent number: 6254802
    Abstract: An improved composition and a method of scavenging oxygen using the composition which comprise oxidizable organic compounds, transition metal catalysts in combination with certain photoinitiators is disclosed. The method comprises initiating scavenging by exposing the composition to UV radiation. The present composition uses certain defined benzophenone derivatives which maintain effectiveness of photoinitiation while providing reduced migration of the photoinitiator from the resin matrix.

  • Patent number: 6110525
    Abstract: A coating composition which forms a peelable coating for protecting surfaces of an object from the outside elements. The coating composition includes a latex of rubber particles and a UV absorber, wherein the rubber particles are present from about 35 to about 50 weight percent in the coating composition. The coating composition may also include from about 0.5 to about 4 weight percent of an antioxidant; from about 0.003 to about 0.03 weight percent of a biocide; from about 0.03 to about 0.08 weight percent of a defoamer; from about 0.07 to about 0.40 weight percent of a thixotropic agent; and a rust inhibitor, wherein all weight percents are based on the total weight of the coating composition. The method of using the composition includes coating the surface with a layer of the above-described coating composition and allowing the layer of coating composition to dry and form a coating which is capable of being peeled from the object.

  • Patent number: 5867549
    Abstract: Methods are provided to at least slow the dissolution of silica in an aqueous environment. In the subject methods, the silica surface is contacted with a multivalent metal cation capable of complexing with oxygen atoms present on the silica surface, where contacting is preferably accomplished by introducing a source of the multivalent metal cation into the aqueous environment. The subject methods find particular use in the inhibition of the dissolution of silica comprising neutron poisoning materials employed in the storage of spent nuclear fuel.
