  • Publication number: 20150073110
    Abstract: The exemplary embodiments disclosed herein relate to activating methods for initiation polymerization of methylene malonates and other polymerizable compositions. The polymerization may be activated by anionic or free radical mechanisms. Because the polymerization may occur very quickly upon contact between the activating agent and the polymerizable composition, methods are provide herein for separating or otherwise rendering the activating agent ineffective to initiate polymerization, until such a reaction is desired. The separation may be physical (separate packaging, separate application steps, encapsulation) or it may be based on latent-activation methods (activation precursors, UV activation). Products formed from the methods disclosed herein may include inks, adhesives, coatings, sealants, reactive moldings, fibers, films, sheets, medical polymers, composites, laminates and the like.

  • Patent number: 7629423
    Abstract: The present invention provides method of preparing alkene-acrylate-norbornene terpolymer by polymerization of a monomer mixture consisting of alkene, acrylate and norbornene by a radical initiator under the presence of a Lewis acid. In the method of preparing the alkene-acrylate-norbornene terpolymer of the present invention, the terpolymer may be prepared in the mild condition of low temperature and low pressure by using the Lewis acid so that the process is simple and the property of the terpolymer may be easily controlled. In addition, the terpolymer prepared by the method includes the ethylene and the norbornene simultaneously so that it has high glass transition temperature, and the brittle property in forming of film is improved.

  • Patent number: 7595369
    Abstract: A method of copolymerizing cyclic olefins and polar vinyl olefins, a copolymer produced by the method, and an optical anisotropic film including the copolymer are provided. According to the copolymerization method, a cyclic olefin and a polar vinyl olefin can be effectively copolymerized using a catalyst system composed of a compound containing a group 13 element and a radical initiator. The resulting copolymer is transparent, and has high adhesion, thermal stability, optical anisotropy and strength, and a low dielectric constant. The optical film including the copolymer can be used as a plastic lens, a polarizer protective film, an adhesive film, and a compensation film, and in a LCD display.

  • Publication number: 20090191362
    Abstract: An optical film has a film a formed of a cyclic olefin resin, and a homeotropically orientated optical anisotropic layer b disposed on the film a. This optical film preferably satisfies the below listed formulae (1) to (3). ?600nm?Rth?200nm??(1) 0nm?R?600nm??(2) NZ?1??(3) (In formulae (1) to (3), Rth indicates the retardation in the thickness direction of the optical film at a wavelength of 550 nm; R indicates the in-plane retardation of the optical film at a wavelength of 550 nm; and NZ indicates (nx?nz)/(nx?ny)). When the optical film is used in an ISP mode liquid crystal display device, light leakage and color fading (discoloration) during black display are prevented stably for a long term, and a good viewing angle compensation effect is obtained (i.e., high contrast ratio at all angles).
