    摘要: A thermotropic liquid crystalline polymer, which is obtainable by copolymerizing a trifunctional hydroxynaphthalene carboxylic acid represented by the general formula (I) and/or reactive derivative thereof with other polymerizing monomer(s) 1 wherein one of m and n is 1 and the other is 2, and a composition including the polymer are provided. The molded article obtained from the thermotropic liquid crystalline polymer or the composition has less anisotropy in mechanical strength and improved weld strength.
