  • Publication number: 20190002717
    Abstract: The ink contains: an ink agent containing a polymer having a chromophore; and a binder resin. The ink preferably further contains water, an antiseptic agent, and/or a hydrotropic agent. The polymer is preferably in a particulate form. The textile printing method includes discharging droplets of the ink to attach the droplets onto a woven fabric and heating the woven fabric obtained after the discharging. The printed textile of the present invention is obtained by the aforementioned textile printing method. The ink agent for textile of the present invention contains a polymer having a chromophore.

  • Patent number: 7528199
    Abstract: A method for producing an alkoxysilyl group-containing conjugated diolefin (co)polymer rubber by polymerizing a conjugated diolefin or a conjugated diolefin and an aromatic vinyl compound in a hydrocarbon solvent by anionic polymerization using as an initiator at least one metal compound selected from an organic alkali metal compound and an organic alkali earth metal compound, and then allowing an alkoxysilane-based compound to react, wherein after the alkoxysilane-based compound has been allowed to react, an alkaline compound is added at the time of desolvation, and treatment is conducted at a pH of 8 to 12.

  • Patent number: 7342070
    Abstract: Disclosed are a conjugated diolefin (co) polymer rubber formed from either a conjugated diolefin or a conjugated diolefin and an aromatic vinyl compound, wherein the (co) polymer rubber has a primary amino group and an alkoxysilyl group which are bonded to a (co) polymer chain; a process for producing the same; a rubber composition; a composite; and a tire. The (co) polymer rubber has satisfactory processability, and can give an automotive tire tread having a balance among wear resistance, failure characteristics, low hysteresis loss and wet-skid characteristics.

  • Patent number: 6812288
    Abstract: The present invention provides a rubber composition that provides excellent vibration-isolating properties, a vibration isolating rubber formed from the rubber composition and a vibration-isolating mount. The rubber composition contains 5 to 40 parts by weight of a styrene-butadiene-based copolymer rubber, having a weight-average molecular weight of 200,000 or less and a glass transition temperature of −35° C. or higher; and 95 to 60 parts by weight of a diolefin-based rubber, having a weight-average molecular weight exceeding 200,000 and a glass transition temperature of −20° C. or lower; where the weight are based on 100 parts by weight of the total amount of both. A vibration-isolating rubber comprising this composition has a performance relationship between a dynamic-to-static modulus ration (Kd/Ks), which is a ratio of a dynamic spring constant (Kd) to a static spring constant (Ks), and a loss factor (tan &dgr;), as shown by the equation (1): Kd/Ks≦20 tan &dgr;−1.8 (1).
