Pref., structural unit I is derived from p-hydroxybenzoic acid; structural unit II, from dihydroxybiphenyl; structural unit III, from 2,6-dihydroxynaphthalene; and structural unit IV, from terephthalic acid. Pref., the molar ratio of the sum of structural units I and II to structural unit III is (60:40)-(95:5).

摘要： PURPOSE:To improve transparency, gas barrier properties and impact resistance of parts of stationery made or a resin of which injection molding is made easy, by preparing a polyester copolymer containing two or more kinds of either one of, or both of, diol components or dicarboxylic acid components. CONSTITUTION:A polyester copolymer is prepared, which contains two or more kinds of either one of, or both of, diol components or dicarboxylic acid components. As the diol components, an ethylen glycol residue and a cyclohexanedimethanol residue are particularly preferable. On the other hand, as the dicarboxylic acid components, a terephtalic acid residue is particularly preferable. When two kinds of the ethylene glycol residue and the cyclohexanedimethanol residue are selected, a molar ratio of 25 to 75 of the former to 75 to 25 of the latter is particularly preferable. In utilizing the characteristic of the polyester copolymer contained in parts of stationery as application of the same, it is preferable to use it for parts of writing utensils, particularly for caps of writing utensils for liquid-base ink.
