  • Patent number: 9023965
    Abstract: Nonconjugated conductive polymers absorb radioactive iodine, therefore are useful for protection against nuclear radiation. These polymers have at least one double bond per repeat unit. The ratio of the number of double bonds to the total number of bonds along the polymer chain is less than half. Examples of nonconjugated conductive polymers include: cis-1,4-polyisoprene (natural rubber), trans-1,4-polyisoprene (gutta percha), polybutadiene, polydimethyl butadiene, poly(b-pinene), styrene butadiene rubber (SBR), polyalloocimene, polynorbornene and many others. Through interaction with iodine atoms the double bonds in the nonconjugated polymers transform into radical cations leading to a dark color. The iodine atoms remain (immobile) bound to the polymer chain through the charge-transfer interaction, these polymers are very inexpensive and can be easily processed into any shape, structure and size. Therefore, these are useful for protection against nuclear radiation including radioactive iodine.

  • Patent number: 8940849
    Abstract: It has been found that certain cells in culture can convert more than about 0.002 percent of the carbon available in the cell culture medium into isoprene. These cells have a heterologous nucleic acid that (i) encodes an isoprene synthase polypeptide and (ii) is operably linked to a promoter. The isoprene produced in such a cultured medium can then be recovered and polymerized into synthetic rubbers and other useful polymeric materials. The synthetic isoprene containing polymers of this invention offer the benefit of being verifiable as to being derived from non-petrochemical based resources. They can also be analytically distinguished from rubbers that come from natural sources. The present invention more specifically discloses a polyisoprene polymer which is comprised of repeat units that are derived from isoprene monomer, wherein the polyisoprene polymer has ?13C value of greater than ?22‰.

  • Publication number: 20140039142
    Abstract: The invention is directed to an extruder (10), particularly for extruding a synthetic rubber product, which comprises a barrel (24), one or several extruder elements (12, 14), particularly one or several extruder screws and/or a kneader elements (14), arranged inside the barrel (24) for conveying the product, optionally an inlet port for feeding a stripping agent into the barrel (24) and an outlet port for removing volatile compounds from the product and, where applicable, the stripping agent. According to the invention a perforated die plate (26) is fixed to the barrel (24) in flow direction before the outlet port. Since the die plate (26) is not fixed to the extruder elements (12, 14) but to the barrel (24) a circumferential clearance between the die plate (26) and the barrel (24) is prevented so that no extruded material is passing the die plate (26) radially outside.

  • Patent number: 8546506
    Abstract: The invention features compositions and methods for producing polymers of isoprene derived from renewable resources such as isoprene produced from cultured cells that use renewable carbon sources. A starting isoprene composition, such as a bioisoprene composition, is distinguished from petroleum based isoprene by the purity profile (such as lower levels of certain C5 hydrocarbons other than isoprene, presence of certain compounds associated with the biological process for production) and the relative content of the carbon isotopes. Polymers obtained by polymerization of such starting isoprene composition according to this invention, such as a polyisoprene homopolymer or a copolymer having repeat units that are derived from isoprene, are distinguishable from isoprene containing polymers from petrochemical resources.
