    • To provide a polyester resin having 1,4-CHDA as the main dicarboxylic acid units, having isomerization of trans-1,4-CHDA suppressed in the esterification and polyconsensation reactions and having a high melting point and excellent heat resistance, and a process for its production. A polyester resin obtainable by preparing an oligomer by an esterification reaction of a dicarboxylic acid component containing 1,4-cyclohexane dicarboxylic acid as the main component, with a diol component, and polycondensing this oligomer in the presence of a polycondensation catalyst; and a process for producing a polyester resin characterized in that the esterification reaction is carried out by means of a basic compound, and then, the polycondensation reaction is carried out by means of a polycondensation catalyst. In the resent invention, T0 and Tp satisfy 0≦{(T0−Tp)/T0}×100≦12 where T0 is the mol % of the trans form in the 1,4-cyclohexane dicarboxylic acid contained in the starting material, and Tp is the mol % of the trans form in the 1,4-cyclohexane dicarboxylic acid units contained in the obtainable polyester resin.
    • 为了提供具有1,4-CHDA作为主要二羧酸单元的聚酯树脂,其在酯化和多缩合反应中抑制反式-1,4- -CHDA异构化并具有高熔点和优异的耐热性, 其生产。 通过以1,4-环己烷二羧酸为主要成分的二羧酸成分的酯化反应制备低聚物和二醇成分得到的聚酯树脂,并在缩聚催化剂的存在下使该低聚物缩聚; 以及一种生产聚酯树脂的方法,其特征在于通过碱性化合物进行酯化反应,然后缩聚反应通过缩聚催化剂进行。 在本发明中,T0和Tp满足0 <= {(T0-Tp)/ T0}×100 <= 12其中T0是起始材料中所含的1,4-环己烷二羧酸中的反式摩尔% Tp是所得聚酯树脂中所含的1,4-环己烷二羧酸单元中的反式摩尔%。
