    Abstract: A metal cord has an M+N construction with two concentric layers. An internal first layer or core includes M wire(s) of diameter d1, M having a value from 1 to 4. An external second layer includes N wires of diameter d2 and is positioned around the core, the N wires being wound in a helix. Between the wires of the two layers are gaps, some or all of which include a filling rubber based on an unsaturated thermoplastic elastomer. The filling rubber may be, for example, based on an SBS or an SIS block copolymer. When used in a molten state, the thermoplastic elastomer presents no problem due to unwanted stickiness if the filling rubber overspills outside the cord after manufacture. The unsaturated and therefore (co)vulcanizable nature of the thermoplastic elastomer makes it compatible with diene rubber matrices used as calendering rubber in metal fabrics intended for reinforcing tires.

    Abstract: The subject invention provides a method for producing essentially homogeneous asphalt compositions which are comprised of the asphalt, a block copolymer (such as a linear block copolymer or a radial block copolymer), and one or more additional desired additives. This method offers the advantage of being capable of attaining the essentially homogeneous asphalt composition in one pass procedure with a short residence time in the mixing equipment. This greatly reduces the thermal history to which heat sensitive asphalt additives, such as asphalt modification polymers, are exposed. It also simplifies the mixing procedure and can reduce the overall amount of energy required to attain the desired blend. In some case, it allows for the production on a commercial basis of asphalt compositions which would otherwise not be feasible, for instance the production of asphalt compositions which contain high levels of asphalt modifications polymers which are otherwise difficult to process.

  • Publication number: 20140364555
    Abstract: The invention relates to unique applications for the novel high melt flow, low viscosity, selectively hydrogenated styrene-butadiene-styrene (hSBS) or selectively hydrogenated controlled distribution styrene-butadiene/styrene-styrene (hSBSS) block copolymers, wherein the melt flow rate of said block copolymer is at least 100 g/10 min at 230° C. under 2.16 kg mass according to ASTM D1238. These block copolymers are novel and have the highest melt flow rate of any styrenic block copolymer also possessing high strength and elasticity. It has applications that prior to the present invention were not normally possible due to the normal low melt flow rate of styrenic block copolymers. The present invention also encompasses various fields of use such as a fiberglass hSBS or hSBSS reinforced mat, low viscosity hSBS or hSBSS coatings for industrial uses, hot melt adhesives prepared from hSBS or hSBSS blended with polyalpha-olefins, and elastic film, fiber, and nonwoven constructions using hSBS or hSBSS.
