| abstract | (57) Abstract: The present invention provides a polymer having a high degree of polymerization only by a melt polymerization method, can be molded by an ordinary molding machine, and has good optical anisotropy, mechanical properties and heat resistance. An object is to obtain a polymerized polyester. [Structure] An oxybenzoyl unit, a 4,4'-dioxybiphenyl unit, and a specific structural unit that essentially requires an ethylenedioxy unit. The structural unit [(I) + (II)] is [(I) + (II) + (III)] above 90 mol% and 95 mol% or less, Structural unit (III) is 5 mol% or more of [(I) + (II) + (III)] 1 It is less than 0 mol% and the molar ratio of structural units (I) / (II) is 7 Logarithmic viscosity of 5/25 to 95/5 (0.1 g / dl concentration, 60 0.5 to 5) measured in pentafluorophenol at ℃ An optically anisotropic copolyester which is dl / g and is substantially insoluble in a mixed liquid of phenol and tetrachloroethane. |
