  • Patent number: 10570249
    Abstract: A process for producing cycloalkenamer-containing compositions involves converting at least one cycloalkene by ring-opening metathetic polymerization to obtain a polyalkenamer-containing product mixture. The product mixture is worked up to remove monomers and oligomers of the cycloalkenes to obtain the polyalkenamer-containing composition by extraction with CO2. The extraction involves at least two stages: an extraction with liquid CO2 under the supercritical conditions, and then an extraction with supercritical CO2. Such cycloalkenamer-containing compositions can be used, for example, in the field of packaging materials, especially for food and drink.

    Abstract: A method for making polyethylene aerogels, including high molecular weight aerogels, commences by in a hydrocarbon solvent (e.g., toluene or benzene) in which polyethylene is insoluble at room temperature, adding polyethylene to the solvent heated to a temperature at which said polyethylene is soluble to form a reaction mixture. A free-radical catalyst is added to the reaction mixture and the reaction mixture is held until the desired gelation of the polyethylene has been achieved. The reaction mixture is cooled to about room temperature; and the hydrocarbon solvent is replaced with a gas (e.g., CO2 or air) to form the polyethylene aerogel. Optionally, the cooled reaction mixture can be contacted with an anti-solvent for polyethylene to replace the hydrocarbon solvent with the anti-solvent. Silica aerogel particles can be encapsulated in polyethylene aerogel by adding the particles to the polyethylene gelation reaction mixture.

  • Patent number: 8759410
    Abstract: This invention aims to provide a thermally foamable microsphere which is excellent in heat resistance, has a high expansion ratio, and shows stable foaming behavior; a method of producing the thermally foamable microsphere; and suitable use thereof. This invention provides a thermally foamable microsphere in which an outer shell encapsulating a foaming agent is formed of a copolymer having a polymethacrylimide structure. In particular, this invention provides a thermally foamable microsphere in which monomers capable of forming the polymethacrylimide structure by a copolymerization reaction are methacrylonitrile and methacrylic acid. Moreover, this invention provides a method of producing the thermally foamable microsphere and use of the thermally foamable microsphere as an additive.

  • Patent number: 8703835
    Abstract: A blowing agent blend for making thermoplastic polymer foams includes methyl formate. The blowing agent blend can further comprise at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent (e.g. an inorganic agent, a hydrocarbon, a halogenated hydrocarbon, a hydrocarbon with polar, functional group(s), water or any combination thereof), or a chemical co-blowing agent, or combinations thereof. The thermoplastic polymer foam can be an alkenyl aromatic polymer foam, e.g. a polystyrene foam. The blowing agent blend includes methyl formate and one or more co-blowing agents. The methyl formate-based blowing agent blends produce dimensionally stable foams that have improved resistance to flame spread. A process for the preparation of such foams is also provided.
