  • Patent number: 9074024
    Abstract: The invention produces suspensions of higher ?-olefins without using cryogenic comminution as well as without using polymer precipitation by adding a non-solvent to a polymer solution. Fine polymer dispersions are produced by thermal re-precipitation of a polymer in a liquid being a non-solvent for that polymer at room temperature and being capable of dissolving the polymer at a higher temperature. The polymer component of a suspension is produced by co-polymerization of higher ?-olefins in a monomer mass in the presence of a Ziegler-Natta catalyst.

    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: 7795361
    Abstract: Provided are a photoreactive polymer that includes a multi-cyclicmulticyclic compound at as its main chain and a method of preparing the same. The photoreactive polymer exhibits excellent thermal stability since it includes a multi-cyclicmulticyclic compound having a high glass transition temperature at as its main chain. In addition, the photoreactive polymer has a relatively large vacancy so that a photoreactive group can move relatively freely in the main chain therein. As a result, a slow photoreaction rate, which is a disadvantage of a conventional polymer material used to form an alignment layer for a liquid crystal display device, can be overcome.

  • Patent number: 6624263
    Abstract: A new polymerization process (atom transfer radical polymerization, or ATRP) based on a redox reaction between a transition metal (e.g., Cu(I)/Cu(II), provides “living” or controlled radical polymerization of styrene, (meth)acrylates, and other radically polymerizable monomers. Using various simple organic halides as model halogen atom transfer precursors (initiators) and transition metal complexes as a model halogen atom transfer promoters (catalysts), a “living” radical polymerization affords (co)polymers having the predetermined number average molecular weight by &Dgr;[M]/[I]0 (up to Mn>105) and a surprisingly narrow molecular weight distribution (Mw/Mn), as low as 1.15. The participation of free radical intermediates in ATRP is supported by end-group analysis and stereochemistry of the polymerization. In addition, polymers with various topologies (e.g.

  • Patent number: RE45219
    Abstract: Provided are a photoreactive polymer that includes a multi-cyclicmulticyclic compound at as its main chain and a method of preparing the same. The photoreactive polymer exhibits excellent thermal stability since it includes a multi-cyclicmulticyclic compound having a high glass transition temperature at as its main chain. In addition, the photoreactive polymer has a relatively large vacancy so that a photoreactive group can move relatively freely in the main chain therein. As a result, a slow photoreaction rate, which is a disadvantage of a conventional polymer material used to form an alignment layer for a liquid crystal display device, can be overcome.
