  • Publication number: 20100256248
    Abstract: According to the present invention there are provided improved rubber modified monovinylidene aromatic polymers having the specified relatively high molecular weight and the necessary rubber levels and particles. These improved resins are specially adapted and suited for use in stretch blow molding processes. They provide improved combinations of container neck strength and toughness, wall strength and stiffness and packaging efficiency. The present invention provides the makers of stretch blow molded containers with options for improved packaging cost and efficiency.

  • Publication number: 20060199872
    Abstract: Foamable compositions and foams comprise at least an ethylene/?-olefin interpolymer. The foam has a density from greater than 150 to about 500 kg/m3. The foamable compositions further comprise a blowing agent and a crosslinking agent. The ethylene/?-olefin interpolymers are a multi-block copolymer comprising at least one soft block and at least one hard block. Methods of making the foamable compositions and foams; and foamed articles made from the foams are also described.

  • Publication number: 20060199911
    Abstract: A polymer composition comprises at least an ethylene/?-olefin interpolymer and at least one other polymer. The other polymer can be selected from a second ethylene/?-olefin interpolymer, an elastomer, a polyolefin, a polar polymer, and an ethylene/carboxylic acid interpolymer or ionomer thereof. The ethylene/?-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. Also provided are gaskets, bottle cap liners, and closures that comprise or obtained from a compositon comprising at least one ethylene/?-olefin interpolymer and at least one polyolefin. The gaskets are capable of compression sealing various containers, without contaminating the contents. Liquid containers particularly benefit from the use of the novel gasket materials disclosed herein.
