  • Patent number: 9637656
    Abstract: The invention provides a composition comprising a first ethylene-based polymer, formed by a high pressure, free-radical polymerization process comprising at least one autoclave reactor, and a second ethylene-based polymer, formed by a high pressure, free-radical polymerization process comprising at least one autoclave reactor, such composition comprising the following properties: A) a melt index (I2) from 2.5 to 10 g/10 min; B) a density from 0.920 to 0.935 g/cc; and wherein the second polymer is present in an amount from 5 to 95 weight percent, based on the sum of the weight of the first polymer and the second polymer; and wherein the density of the of the second polymer is greater than the density of the first polymer, and wherein the first polymer has a melt index I2 greater than 2.5 g/10 min.
    Type: Grant

  • Patent number: 8592017
    Abstract: Stretch blow molded articles, e.g., thin wall containers, are made from a polymer blend comprising at least 70 percent by weight HDPE and at least 10 percent by weight LDPE based upon the total weight of the polymer blend. The HDPE/LDPE blends used in the practice of this invention provide increased melt strength resulting in a wider processing window.

  • Patent number: 8334362
    Abstract: An apparatus and method for determining the standardized melt elasticity (sME) force of a thermoplastic polymer needed to stretch a strand of melted polymer at a speed about thirty three times faster than the speed of strand formation from a body of melted polymer under constant stress from an unencumbered dead weighted piston.

  • Publication number: 20100126909
    Abstract: The invention provides a method for removing mercury from a liquid or gas hydrocarbon stream, mixtures thereof, including mixtures of liquid streams with a solid carbonaceous substance, by contacting the hydrocarbon stream with a composition comprising silver and a support material, wherein the composition as measured by ammonia chemisorption has a surface acidity in the range of 0.1-10.0 ?mole of irreversible NH3/g of the composition.

  • Patent number: 7271202
    Abstract: The invention is a reactive hot melt composition which has excellent adhesion and curing properties, and can be formulated into free-flowing pellets or beads, by using an ethylene-acrylic acid copolymer, and athylene-methacrylic acid copolymer, and/or an ethylene-acrylic acid methacrylic acid terpolymer as a component of the composition along with free radical crosslinking initiators. The incorporation of a foaming agent enables the production of compositions which are useful in space-filling applications, (i.e., as so-called “anti-flutter” compositions).
