Abstract: PURPOSE:To obtain a melt-moldable aromatic polyester excellent in heat resistance and flow, comprising three specified kinds of structural units. CONSTITUTION:This heat-resistant aromatic polyester comprises three kinds of structural units of formulas I, II and III, wherein structural units (I) amount to 55-80mol% based on the total, structural units [II+III] amount to 45-20mol% based on the total and the molar ratio of structural units (II) to structural units (III) is 1-5. In formulas I-III, X is at least one group selected from among groups of formulas IV and V, etc., and Y is at least one group selected from among groups of formulas VI and VII, etc., provided that the case where Y is a group of formula VI when X is at least one group selected from groups of formulas IV and V is excluded. Said polyester can be produced by, for example, subjecting an aromatic dihydroxy compound such as p- hydroxybenzoic acid or t-butylhydroquinone, a dicarboxylic acid such as terephthalic acid and acetic anhydride to a polycondensation reaction by elimination of acetic acid.

Abstract: PURPOSE: To obtain a copolyester which can be prepared as a polymer having a high degree of polymerization through melt polymerization only, is moldable with an ordinary molding machine, and is excellent in optical anisotropy, heat resistance, and mechanical properties by constituting the copolyester of specific kinds of structural units in specific proportions. CONSTITUTION: The optically anisotropic copolyester which is made up of structural units I to IV respectively represented by formulae I to IV (wherein R1 is a group of formula V, and R2 is a group of formula VI, V, or VII), the molar amount of the sum of the units II and III being substantially equal to that of the units IV, the sum of the units I and II accounting for more than and 90 or less 95mol% of the sum of the units I, II, and III, the amount of the units III accounting for 5 or more and less than 10mol% of the sum of the units I, II, and III, and the molar ration of units I/units II being 75/25 to 95/5. It has an inherent viscosity (as measured in pentafluorophenol at a concentration of 0.1g/dl at 60 deg.C) of 0.05-5dl/g, and is substantially insoluble in phenol/tetrachloroethane mixture. This copolyester an be obtained as a polymer having a high degree of polymerization through melt polymerization only. It gives a molding excellent in heat resistance and mechanical properties and is hence usable in various applications such as metal substitutes and extrudates.

Abstract: PURPOSE:To obtain a high polymerization degree polymer only by melting and polymerization, and to manufacture the title moldable injection molded form having excellent optical anisotropy, heat resistance, rigidity and shock resistance by a normal molding machine by injection-molding copolymerized polyester consisting of a specific structural unit. CONSTITUTION:[(I)+(II)] in the structural unit formulae (I)-(III) of copolymerized polyester occupy 77-95mol% of the whole, and the mol ratio of (I)+(II) extends over 75/25-95/5. These condensation polymerization reactions are accelerated even in a noncatalytic manner, but it is preferable that a metallic compound such as stannous acetate, tetrabytultitanate, sodium acetate and potassium acetate, antimony trioxide, metallic magnesium, etc. is often added. Said copolymerized polyester is injection-molded. The thermal deformation temperature (load 18.6kg/cm ) of 150 deg.C or higher of an injection molded form is required.
