There are provided a compound having a thermotropic liquid crystalline structure and a polyethylene glycol polymer. The compound is obtained by modifying an epoxide functional group in a thermotropic liquid crystalline molecule. The polyethylene glycol polymer is obtained by ring-opening polymerization thereof. The polyethylene glycol main chain polymer is easy to form in thin film, bulk, or fiber form, and has a high thermal conductivity and thus can be used alone or in the form of a composite material as a heat-dissipating polymer.

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.
