Abstract: PURPOSE:To improve the heat resistance, the toughness of the knife edge, and the adhesive strength to fluororesin paint by using fusion-moldable liquid crystal polyester which consists of four specific structure units so that the ratio of the 1st structure unit to the sum of the 1st - 3rd structure units and the mole ratio of the 2nd and 3rd structure units are specified. CONSTITUTION:The fusion-moldable liquid crystal polyester which consists of the structure units shown by formulas I - IV so that the structure unit shown by the formula I has a 40 - 90% mole ratio to the sum of the structure units shown by the formulas I - III and the mole ratio of the structure units shown by the formulas II and III is 9/1 - 1/9. In the formula III, R1 is the group of the formula V and in the formula IV, R2 is >=2 kinds selected from the formulas VI and VII. In the formula VI, X is a hydrogen atom or chlorine atom. Consequently, the separating claw is obtained which has the superior heat resistance, low water absorptivity, superior paper discharging ability, and adhesive strength of fluororesin paint while its knife edge is hard to deform even at high temperature and high humidity.
