  • Patent number: 9550839
    Abstract: The present invention achieves increased filler interaction by incorporating a small amount (a few units per chain of rubbery polymer) of a conjugated triene monomer, such as alloocimene, randomly throughout the polymer chain of a rubbery polymer or at the chain ends of the rubbery polymer. The incorporation of the conjugated triene monomer leads to the formation of a polymer containing highly reactive conjugated diene units. These conjugated diene units can chemically react with carbon black leading to superior reinforcement. Alternatively, these conjugated diene units can be used for functionalization of the polymer with silica interactive/reactive groups using Diels Alder reactions. This functionalization of the rubbery polymer can conveniently be conducted in a mixer, such as a Banbury mixer, a mill mixer, or the like.

  • Patent number: 7868111
    Abstract: The present invention provides a method for producing ?-olefin polymer, comprising polymerizing ?-olefins in the presence of a halogen atom-containing acid catalyst by use of an aliphatic hydrocarbon having 3-12 carbon atoms, which contains 5 to 95 mass % of ?-olefin, as a raw material; removing catalyst residue and halogen-containing compounds by bringing a product in the polymerization step into contact with an aluminum atom-containing inorganic solid treatment agent with or without deactivating the catalyst; and separating the ?-olefin polymer. According to this method, the catalyst residue and other halogen-containing compounds can be removed, without relying on aqueous deactivation and separation steps using an alkaline aqueous solution or the like, from a polymerization reaction product obtained by polymerization in the presence of a halogen-containing acid catalyst by use of an ?-olefin-containing liquid hydrocarbon as a raw material.

  • Patent number: 7851577
    Abstract: A cationic polymerization process for isoolefins using a zinc halide initiator. The zinc halide initiator is added to a solution of the isoolefin in a suitable solvent, preferably a halocarbon solvent. Polymerization reactions are normally conducted at temperatures high enough to allow the zinc halide initiator to dissolve in the solution. An alkyl halide activator may optionally be used and is preferably added to the solution prior to the zinc halide initiator. A multiolefin may optionally be present in the solution. The process is particularly useful in the formation of isoolefin homopolymers and co-polymers of isoolefins and multiolefins, such as butyl rubber.

    Abstract: The present invention relates to colloidal photonic crystals using colloidal nanoparticles and a method for the preparation thereof, wherein by adding a viscoelastic material into a solution containing the colloidal nanoparticles when preparing the colloidal photonic crystals, a uniform volume contraction occurs due to the elasticity of the viscoelastic material even when a nonuniform volume contraction occurs while drying a dispersion medium in the colloidal solution. Thus, it is possible to prepare 2 or 3 dimensional colloidal photonic crystals of large scale with no defects in less time.
