    摘要: A polymer blend composition for preparing a negative C-plate type optically anisotropic film, a negative C-plate type optically anisotropic film prepared from the composition, and an LCD device containing the film are provided to prepare a negative C-plate type optically anisotropic film simply with low cost without coating process. A polymer blend composition for preparing a negative C-plate type optically anisotropic film comprises at least one kind of a polymer having a negative birefringence index; and 1-50 wt% of at least one kind of a polymer having a positive birefringence index, wherein the change of glass transition temperature according to the content of the polymer having a positive birefringence index is 2 deg.C or less. Preferably the polymer having a negative birefringence index is a cyclic olefin-based addition polymer or a norbornene-based polymer.

    摘要: A method for preparing a cyclic olefin polymer having a high bulk density is provided to obtain a cyclic olefin polymer with a high density through precipitation even when the polymer contains monomers having linear or branched alkyl groups in an amount of 15 mol% or lower. A method for preparing a cyclic olefin polymer having a high bulk density comprises the steps of: (a) polymerizing at least one cyclic olefin monomer, or at least one cyclic olefin monomer and ethylene to provide a solution of cyclic olefin polymer solution; (b) diluting the solution of cyclic olefin polymer solution with a solvent including a cyclic nonpolar solvent; (c) adding a non-solvent dropwise to the diluted solution of cyclic olefin polymer to precipitate the cyclic olefin polymer; and (d) filtering the precipitated cyclic olefin polymer.

    摘要: The present invention provides a radically polymerizable compound having an air-drying group, a radically polymerizable unsaturated group and an alkyl group having 14 or more carbon atoms. The radically polymerizable compound can give an excellent surface drying property and storage stability when added to a radically polymerizable resin composition. The air-drying group and the radically polymerizable group are obtained desirably by using, as materials, one or more compounds selected from a group consisting of cyclic unsaturated aliphatic polybasic acid and derivatives thereof; compounds having an allyl ether including an alpha-hydrogen; compounds of alcohol decomposition obtained by the esterification of polyhydric alcohol and drying oil; and compounds having a dicyclopentadienyl group including an hydroxyl group. The alkyl group is obtained desirably by using, as materials, alcohol having 14 or more carbon atoms and/or carboxylic acid.
