  • Patent number: 8501308
    Abstract: Thermoplastic polymer compositions, films, continues, closures, laminates can comprise a modified vinyl polymer said modified polymer having a moiety comprising a cyclodextrin compound. The cyclodextrin compound, locked into the polymer structure, can absorb impurities, permeants, or other undesirable volatile materials. The cooperation between the cyclodextrin grafted onto the thermoplastic polymer and the polymer structure can provide barrier properties to a film, web or other polymer structure. A permeant or a contaminant can be complexed or trapped within the polymer and held within the film or Web preventing the permeant or contaminant from passing into the interior of a container or enclosure.

  • Patent number: 8470946
    Abstract: Carbon nanotube (CNT) yarns and sheets having enhanced mechanical strength using infused and bonded nano-resins. A CNT yarn or sheet is surface-activated to produce open bonds in the CNT walls prior to resin infusion. The CNT yarn or sheet is infused with a low viscosity nano-resin that penetrates spaces between individual CNTs and is cured to cross-link and chemically bond to the CNT walls, either directly or through a functional molecule, to bond the individual CNTs or ropes to each other. The nano-resin can comprise dicyclopentadiene having an uncured viscosity near that of water. The cross-linking process involves ring-opening metathesis polymerization and catalysis of the nano-resin in combination with a functionalizing material such as norbornene, to enhance bonding between the carbon and nano-resin. The process increases load capability, tensile strength, and elastic modulus of the yarns and sheets, for use as a structural component in composite materials.

The elastic material contains a crosslinked network formed from a linear block copolymer having a monoalkenyl aromatic midblock positioned between conjugated diene endblocks (e.g., butadiene-styrene-butadiene (“B-S-B”) triblock copolymer). Prior to crosslinking, such linear block copolymers have a relatively low viscosity and thus may be readily formed into a precursor elastic material (e.g., film, strands, web, etc.) that is subsequently crosslinked to achieve the desired elastic and mechanical properties. Crosslinking is typically achieved through the formation of free radicals (unpaired electrons) that link together to form a plurality of carbon-carbon covalent bonds at the conjugated diene endblocks.

  • Patent number: 8148473
    Abstract: Disclosed is a sulfur-containing conjugated diolefin copolymer rubber composed of a conjugated diolefin and an aromatic vinyl compound, wherein (1) the content of sulfur bound to the rubber is 0.01 mmol % or more, (2) the content of the aromatic vinyl compound polymerization unit is not less than 5 wt % and less than 45 wt % relative to the amount of the copolymer rubber, and (3) the content of a vinyl bond (a 1,2-bond) in the conjugated diolefin polymerization unit is 30 mol % or more relative to the amount of the conjugated diolefin polymerization unit. In the copolymerization between the conjugated diolefin and the aromatic vinyl compound, a sulfur-containing polymerization terminator is used to terminate the reaction of the copolymerization.

  • Patent number: 8138265
    Abstract: A dihydroxyphenyl cross-linked macromolecular network is provided that is useful in artificial tissue and tissue engineering applications, particularly to provide a synthetic macromolecular network for a wide variety of tissue types. In particular, artificial or synthetic cartilage, vocal cord material, vitreous material, soft tissue material and mitral valve material are described. In an embodiment, the network is composed of tyramine-substituted and cross-linked hyaluronan molecules, wherein cross-linking is achieved via peroxidase-mediated dityramine-linkages that can be performed in vivo. The dityramine bonds provide a stable, coherent hyaluronan-based hydrogel with desired physical properties.

  • Patent number: 8093338
    Abstract: Provided is an eucommia-derived biopolymer, which is obtained by biologically decaying an eucommia to obtain an eucommia decomposition product, and washing the eucommia decomposition product. The biopolymer is obtained by such a convenient method, and contains mainly a trans-isoprenoid and has a relatively high molecular weight. Therefore, the biopolymer is solid and elastomeric, and is useful as an industrial material.

  • Patent number: 8080260
    Abstract: A composition comprising a human- or animal-derived extracellular matrix and a macromolecular network which is prepared ex vivo is provided that is useful in the repair of a tissue injury, particularly in repair of tears or gaps between a tendon and a bone, such as in a rotator cuff tear. In an embodiment, the composition comprises a human- or animal-derived extracellular matrix having impregnated therein a macromolecular network of hyaluronan macromolecules that have been cross-linked via dihydroxyphenyl linkages, so that the cross-linked network is interlocked within the extracellular matrix. The resulting HA-incorporated extracellular matrix can be supplied in the form of a patch to reinforce a tissue repair or cover a tissue defect.

  • Patent number: 8017694
    Abstract: Nonconjugated conductive polymers, which are all polymers that have a ratio of double bonds to total bonds of less than ½ are doped with iodine to produce compositions with unexpected characteristics in this invention. The mechanical and elastomeric properties of a nonconjugated polymer can be enhanced by doping the polymer with an electron acceptor such as iodine, in order to cure the polymer. Among the nonconjugated polymers are the cis-1,4-polyisoprene, cis-1,4 polybutadiene, styrene-butadiene copolymers (SBR), ethylene-propylene-diene monomer and poly (?-pinene). A heated mixture of iodine and sulfur produces a faster rate of vulcanization of rubber than using sulfur alone.
