  • Articles prepared from hydrogenated controlled distribution block copolymers
    Patent number: 7267855
    Abstract: The present invention relates to articles prepared from novel anionic block copolymers of mono alkenyl arenes and conjugated dienes, and to blends of such block copolymers with other polymers. The block copolymers are selectively hydrogenated and have mono alkenyl arene end blocks and controlled distribution blocks of mono alkenyl arenes and conjugated dienes. The block copolymer may be blended with at least one other polymer selected from the group consisting of olefin polymers, styrene polymers, amorphous resins and engineering thermoplastic resins.
    Type: Grant

  • Modified styrenic block copolymer compounds having improved elastic performance
    Patent number: 6630532
    Abstract: The present invention is an improved block copolymer composition for extruding films having excellent stress relaxation and increased retained tension or load at elevated temperatures. The compound is comprised of: (a) from 52 to 60 percent by weight of a block copolymer having at least two polystyrene endblocks and a midblock of hydrogentated polymerized butadiene which has a vinyl content of 45 percent by weight or less (b) from 13 to 22 percent by weight of polystyrene, and (c) from 19 to 28 percent by weight of oil.
