  • Patent number: 9023965
    Abstract: Nonconjugated conductive polymers absorb radioactive iodine, therefore are useful for protection against nuclear radiation. These polymers have at least one double bond per repeat unit. The ratio of the number of double bonds to the total number of bonds along the polymer chain is less than half. Examples of nonconjugated conductive polymers include: cis-1,4-polyisoprene (natural rubber), trans-1,4-polyisoprene (gutta percha), polybutadiene, polydimethyl butadiene, poly(b-pinene), styrene butadiene rubber (SBR), polyalloocimene, polynorbornene and many others. Through interaction with iodine atoms the double bonds in the nonconjugated polymers transform into radical cations leading to a dark color. The iodine atoms remain (immobile) bound to the polymer chain through the charge-transfer interaction, these polymers are very inexpensive and can be easily processed into any shape, structure and size. Therefore, these are useful for protection against nuclear radiation including radioactive iodine.

  • Patent number: 8846803
    Abstract: The invention relates to polymeric latexes that can be used in adhesive compositions, which provide improved bonding of rubber articles to rubber reinforcing articles. The adhesive composition includes a single or a blend of polymeric latexes comprising a conjugated aliphatic monomer, a vinylaromatic monomer, a vinylpyridine monomer, and a nitrogen-containing monomer comprising a reactive N-methylol- or N-alkoxy-functionality. Use of the monomer comprising a nitrogen-containing monomer comprising a reactive N-methylol- or N-alkoxy-functionality allows for reduced amounts of the vinylpyridine monomer in the latex, and enhances the bonding properties of the adhesive composition. Use of the adhesive composition provides economic and chemical advantages for the preparation of reinforced rubberized articles.

    Abstract: A method for manufacturing a polymer includes the steps of: (1) deciding an upper limit of a budget; (2) deciding an amount of a non-fossil resource-derived monomer and an amount of a fossil resource-derived monomer such that utility is optimized in a range where a cost does not exceed the upper limit, by using a function that includes a total monomer amount and a utility index of the non-fossil resource-derived monomer as constants and includes the amount of the non-fossil resource-derived monomer and the amount of the fossil resource-derived monomer as variables; and (3) polymerizing the non-fossil resource-derived monomer and the fossil resource-derived monomer.

  • Patent number: 8729204
    Abstract: Compositions and methods for producing polymerization initiators comprising at least two protected primary amine groups. Polymers prepared using such polymerization initiators can comprise a residue of the polymerization initiator and can initially comprise the at least two protected primary amine groups. Such polymers can undergo a deprotection process thereby yielding a polymer having one or more unprotected primary amine groups. Polymers having primary amine groups can be employed in rubber compositions, which have a variety of potential applications, such as, for example, in tire manufacturing.

  • Patent number: 8716409
    Abstract: A composition includes a baleable polymer resulting from the polymerization of at least one conjugated diene in the presence of an anionic initiator. The baleable polymer has carboxylate termination resulting from the addition of carbon dioxide to terminate the polymerization reaction. The polymer has Mooney ML1+4 viscosity of >35 and a solution viscosity of X, where X is >75 cP. The addition of an lonolizer to a composition that includes the polymer reduces the solution viscosity of the polymer from X to Y where Y meets the following formula: 0.4X?Y?0.58X. The baleable polymer is blended with impact-modified plastics resulting in improved izod values and optical qualities. Processes for making and utilizing the polymer composition, and ionolizer are also described.

  • Patent number: 8691994
    Abstract: The invention provides a composition and a method of using the composition for inhibiting the unwanted polymerization of ethylenically unsaturated monomers. The composition is prepared by reducing a nitroxide stable free radical to its corresponding hydroxylamine through reaction with a dialkyl/aryl hydroxylamine and subsequent addition of a polymerization prevention component selected from phenolic antioxidants, phenylenediamine and phenylenediamine derivatives, or phenothiazine and phenothiazine derivatives targeted towards ethylenically unsaturated monomers. The conversion of the nitroxide by the dialkyl/aryl hydroxylamine is to prevent it or the polymerization prevention component from being “spent”by reaction with each other, impurities or any other incompatible components. This allows previously incompatible combinations to now work effectively. In fact, the combination is more efficacious as the combination exerts a synergy due to the presence of various polymerization prevention reagents.

    Abstract: An apparatus for forming particles from a liquid, including a rotor assembly having at least one surface sized and shaped so as to define at least one capillary. Each capillary has an inner region adjacent an axis of rotation of the rotor assembly, an outer region distal from the axis of rotation, and an edge adjacent the outer region. The rotor assembly is configured to be rotated at an angular velocity selected such that when the liquid is received in the inner region of the at least one capillary, the liquid will move from the inner region to the outer region, adopt an unsaturated condition on the at least one surface such that the liquid flows as a film along the at least one surface and does not continuously span the capillary, and, upon reaching the edge, separates from the at least one surface to form at least one particle.

  • Publication number: 20140069033
    Abstract: This invention relates to a flora barrier member for a grave marker, the combination of a flora barrier member and a grave marker, and a method of erecting a grave marker. Many cemeteries have banned the use of temporary grave markers as they are prone to damage and increase the amount of time required to maintain the cemetery. This is due to the fact that extra time must be taken to remove the grass and weeds in the vicinity of the base of the grave marker. The present invention provides a flora barrier member that prevents grass or weed growth in this area. The flora barrier member is simple to construct and install and will allow the use of temporary grave markers in most cemeteries.
