  • Patent number: 9353292
    Abstract: The invention relates to a method for modifying an asphalt binder using, as an additive, a nanocomposite of: functionalized multi-walled carbon nanotubes dispersed in a styrene-butadiene-styrene polymer matrix (SBS/MMWCNT). The asphalt modified with the SBS/MMWCNT nanocomposite has substantially improved mechanical resistance to deformations and to loads at high temperatures, such that the life of the flexible paving is improved. The asphalt mixtures produced with this novel modified asphalt binder have considerably less rutting, are classified as high-modulus asphalt mixtures when produced from asphalt of medium (60/70) or greater hardness, and are not sensitive to moisture effects.

  • Publication number: 20150087778
    Abstract: A method and system for formation of a polyarylene sulfide is described. The method includes a first stage in which a complex is formed in a reactor. The complex includes the hydrolysis product of an organic amide solvent and an alkali metal hydrosulfide. The complex formation reaction also forms hydrogen sulfide as a by-product. The method also includes treating a fluid stream that is pulled off of the reactor. The treatment includes scrubbing the fluid stream to recover hydrogen sulfide from the stream and return the hydrogen sulfide to the reactor. The recovery and recycle of the hydrogen sulfide can prevent loss of sulfur from a polyarylene sulfide formation process.

Methods include means for initiating the polymerization of aminoacid-N-carboxyanhydride (NCA) monomer by combining the monomer with an amido-containing metallacycle, for making self assembling amphiphilic block copolypeptides and related protocols for adding oligo(ethyleneglycol) functionalized aminoacid-N-carboxyanhydrides (NCAs) to polyaminoacid chains. Additional methods include means of adding an end group to the carboxy terminus of a polyaminoacid chain by reacting an alloc-protected amino acid amide with a transition metal-donor ligand complex to forming an amido-amidate metallacycle for use in further polymerization reactions. Novel compositions for use in peptide synthesis and design including five and six membered amido-containing metallacycles and block copolypeptides are also disclosed.

  • Patent number: 8101838
    Abstract: A method of forming dispersed water-soluble quantum dots and tuning water-soluble quantum dot aggregate size by providing a plurality of water-soluble quantum dots in a dispersion, the plurality of water-soluble quantum dots are modified with an amphiphilic polymer, and by adding an amount of the amphiphilic polymer to the dispersion such that the ratio of the amphiphilic polymer units to quantum dots is maintained higher to obtain dispersions of smaller quantum dot aggregates and kept lower to obtain dispersions of larger quantum dot aggregates.

  • Publication number: 20110190442
    Abstract: The disclosures herein relate to a polymer such as nylon 66, having low yellowness and excellent whiteness retention for applications in melt extrusion and injection molding where an increase in molecular weight is not desirable. The polymer is prepared with a phosphorus compound content, e.g., a sodium hypophosphite (SHP) content, in an amount of 150 to 300 ppm by weight. The presence of an “end cap” additive such as one selected from acetic acid, propionic acid, benzoic acid, or succinic acid, added at the start of polymerization, effectively mitigates undesired molecular weight gain.
