  • POLYMERIZABLE COMPOUND HAVING LATERAL SUBSTITUENT IN TERMINAL RING STRUCTURE
    Publication number: 20150361190
    Abstract: An object of the invention is to provide a polymerizable compound having small refractive index anisotropy and having high storage stability and high alignment properties when constituting a polymerizable liquid crystal composition, and provide a polymerizable liquid crystal composition containing the polymerizable compound. Further, the object is to provide a polymer produced by polymerizing the polymerizable liquid crystal composition and an optically anisotropic body including the polymer. The present invention provides a polymerizable compound represented by general formula (I), a polymerizable liquid crystal composition containing the compound as a constituent component, and further provides a polymer produced by polymerizing the polymerizable liquid crystal composition and an optically anisotropic body including the polymer.
    Type: Application
