Non-metal Phosphorus-containing Material Patents (Class 526/145)
  • Patent number: 10343152
    Abstract: The oligomerization of ethylene using a chromium (Cr) catalyst having a phosphorus-nitrogen-phosphorus (P—N—P) ligand is known. Reactor fouling with by-product polyethylene can be severe at operating temperatures of greater than 60° C. However, the activation of such catalysts in a continuous flow reactor at low temperatures can be difficult and activity can be low. We have now discovered that highly active Cr/P—N—P catalysts may be prepared and activated in-situ (i.e. directly in the polymerization reactor) at low temperatures (from about 30 to about 45° C.) by combining the Cr; the P—N—P ligand and an aluminoxane in the process solvent in the presence of hydrogen. The use of hydrogen allows very high productivity (greater than 1×106 grams of ethylene conversion per gram of Cr) at low temperature. We have also observed reactor fouling rates as low as 2 to 10 parts per million of polyethylene per hour (based on total ethylene conversion) using this process.

    Abstract: The present invention relates to a norbornene polymer that comprises a norbornene monomer having a photoreactive functional group, and a method of manufacturing the same. The norbornene polymer comprises at least 50 mol % of exo isomers among the norbornene monomers having the photoreactive functional group. Since the norbornene polymer according to the present invention comprises at least 50 mol % of exo isomers among the norbornene monomers having the photoreactive functional group, a molecular weight is significantly increased while the yield is not reduced during the manufacturing of the polymer. In views of the three dimensional structure, stability is ensured because the polymer has a planar structure in which the photoreactive groups between the molecules are close to each other. Therefore, the distance between the photoreactive groups is reduced, thus increasing the photoreaction rate.

  • Patent number: 7964680
    Abstract: Disclosed is a method of producing a cyclic olefin polymer having a polar functional group, an olefin polymer produced by using the method, an optical anisotropic film including the olefin polymer, and a catalyst composition for producing the cyclic olefin polymer. In the olefin polymerization method and the catalyst composition for polymerization, since deactivation of the catalyst due to polar functional groups of monomers is capable of being suppressed, it is possible to produce polyolefins having a high molecular weight at high polymerization yield during polyolefin polymerization. Furthermore, the cyclic olefin having the polar functional groups has excellent polymerization reactivity and the activity of the catalyst composition including the same is maintained under a variable polymerization condition. Accordingly, the present invention is very useful for a mass-production process.

  • Patent number: 7825199
    Abstract: Further improvements have been made in processes for controlled polymerization of free radically (co)polymerizable monomers mediated by a transition metal complex participating in a redox reaction which involves transfer of a radically transferable atom or group to and from an initiator or dormant polymer and the growing active polymer chain ends. Two improvements involve the choice of counterion in the transition metal complex. In one improvement the transition metal is held in close conjunction with a solid support through interaction with a counterion directly attached to the support. This cognition also allows for improvements in catalyst utilization including catalyst recovery and recycle. In another improvement, particularly suitable for controlled polymerization of certain monomers with an expanded range of transition metals, the function of counterion and ligand in the development of the transition metal based catalyst is superseded by use of salt containing a soluble organic counterion.
