  • Publication number: 20150112000
    Abstract: The presently disclosed and claimed inventive concept(s) relates to a method for making a particular product comprising a nonionic synthetic associative (NSAT) rheology modifier and a dissolution promotion water soluble additive. The method comprising the steps of: (a) obtaining the NSAT theology modifier and the dissolution promotion water soluble additive; (b) melting the NSAT theology modifier and the dissolution promotion water soluble additive; (c) mixing the molten NSAT theology modifier and the dissolution promotion water soluble additive; and (d) producing the particulate product from step (c). The NSAT rheology modifier is selected from the group consisting of hydrophobically-modified ethoxylated urethane (HEUR), hydrophobically-modified polyethylene glycol (HMPEG), and hydrophobically-modified polyacetal-polyether (HMPAPE). The particulate product prepared from the method is incorporated into a waterborne paint formula.

  • Patent number: 8173799
    Abstract: A composition of a loose mass of comminuted raw cotton linter fibers has a bulk density of at least 8 g/100 ml and at least 50% of the fibers in the mass passes through a US standard sieve size #10 (2 mm opening). This composition is made by obtaining a loose mass of first cut, second cut, third cut, or mill runs raw cotton linters or mixtures thereof and comminuting the loose mass of raw cotton linters to a size wherein at least 50% pass through a US standard sieve size #10 (2 mm opening). This composition is used to make cellulose ether derivatives.

  • Patent number: 7932309
    Abstract: A water-borne coating composition containing an ether derivative of raw cotton linters (RCL), a latex polymer, and water in which the ether derivative RCL provides improved rheological properties when compared to analogous cellulose ether compounds produced from more refined cellulose sources while not substantially degrading the coating composition's aesthetic qualities.

  • Patent number: 7562419
    Abstract: An improved process for the purification of raw cotton linters includes the cutting of a first, second, third or mill run cut raw cotton linters to a particle size that passes through a 2,500 micrometer screen and then mechanically separating the linters into clean and unclean fractions. The clean fraction contains purified cut raw cotton linters and the unclean fraction contains the impurities.

  • Patent number: 5877848
    Abstract: Printing plates are formed from a layer of photopolymerizable resin by a process and assembly which involves moving a resin layer past a variable intensity light source so as to sequentially and selectively cross-link the resin layer as the resin layer moves past the light source.

  • Patent number: 5573721
    Abstract: A system is provided for producing a three dimensional object from a reactive liquid medium capable of being solidified. The object is constructed from many successive layers of the solidified reactive liquid medium when subjected to appropriate synergistic stimulation. A reservoir contains both the reactive liquid medium and an underlying supporting, substantially immiscible, non-reactive liquid medium. To begin forming the object, a platform within the reservoir is initially positioned at a depth equal to the thickness of a first layer to be solidified, and continues to support the object being constructed. The synergistic source radiates toward the reactive liquid medium and imaging apparatus defining a three dimensional object of required configuration selectively controls the size and shape of that part of a new two dimensional layer to be solidified. At least part of the new layer is solidified, after which a further layer is applied.

  • Patent number: 5152946
    Abstract: Biaxially oriented film is post-treated by an annealing process in a limited temperature range of 45.degree. C. to 120.degree. C. for various time periods based on the temperature for annealing in order to produce a film having less than a 0.2% shrinkage in the machine direction as measured at 51.7.degree. C. for 24 hours. This film has a wide range of uses, such as overwrapping film.

  • Patent number: 4820519
    Abstract: Plant material such as tobacco is protected during storage by enveloping the plant material in a thin film that is composed of a polymeric material and isopropyl-(E,E)-11-methoxy-3,7,11-trimethyl-2,4-dodecadienoate (hereinafter referred to as "methoprene"). Air moves within the envelope carrying methoprene that has migrated from the surface of the film to the surface of the plant material. The thin film is a biaxially oriented polyolefin that has a thickness of from 0.01 to 0.2 mm and has from about 100 to 20,000 ppm of said methoprene incorporated therein.
