  • Patent number: 7776943
    Abstract: A method for forming a nanocomposite by olefin polymerization in which at least one cation-exchanging layered load material, selected from the group consisting of cation-exchanging, layered inorganic silicates and cation-exchanging, layered compounds other than silicates, is treated with acid to disrupt its layered structure and is combined with a catalyst that becomes activated for olefin polymerization when in contact with the acid-treated filler. An olefin is contacted by the activated catalyst—filler combination either (a) in the absence of an alkylaluminum co-catalyst or (b) with an alkylaluminum co-catalyst when the activatable catalyst is a polyalkylmetal compound, to form a nanocomposite containing polyolefin and the acid-treated filler. In a particular embodiment, sufficient filler is used to constitute at least 30 weight % of the nanocomposite to prepare a highly loaded nanocomposite masterbatch.

  • Patent number: 7704423
    Abstract: An injection-foaming molding process for manufacturing a formed article by injecting a molten resin containing a foaming agent into a cavity of a mold being retained in an openable state and then expanding the cavity by opening the mold to allow the resin to foam includes: i) a step of discontinuing a cavity of a mold from a resin-reserving section located at front end of a screw immediately after the completion of injection of a molten resin containing an expandable resin into the mold cavity; and ii) a step of keeping the resin-reserving section under pressure at least equal to back pressure for charging during a period from the completion of injection to start of charging the molten resin containing the expandable resin for next shot, decreasing pressure in the resin-reserving section to back pressure for charging, and then starting the charging.
