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 improve the elastic modulus and hot-water resistance of a crystalline polyester, without lowering the crystallinity, by adding a specific aromatic ester. CONSTITUTION:100 parts by weight of a linear crystalline polyester (e.g. polyethylene terephthalate) is compounded with 0.1-20 parts of an aromatic ester of formula I or II (R is alkyl, alkoxy, ester, etc.) having a characteristics of a liquid crystal with a nematic melting point of >=120 deg.C. For example, the liquid crystal compound is mixed with the polyester by an extruder, a kneader, etc., or is attached to the pellets of the polyester. EFFECT:Useful for manufacturing of film, tape, bottles, and food containers.
