  Process for the preparation of a modified polybutylene terephthalate resin which generates little gas such as tetrahydrofuran in high-temperature service and a reduced amount of sublimate when melted. The polyester is prepared from an acid component comprising terephthalic acid or a lower alcohol ester thereof as the main component and a diol component comprising 1,4-butanediol as the main component through esterification or transesterification and polycondensation, in which 0.001 to 0.5 mole% (based on the acid component) of at least one specific aromatic sulfonic acid compound is added before the completion of the polycondensation.

  一种改性聚对苯二甲酸丁二醇酯树脂的制备工艺，该树脂在高温下使用时产生的四氢呋喃等气体很少，熔化时产生的亚甲烷量也较少。该聚酯是由以对苯二甲酸或其低级醇酯为主要成分的酸组分和以 1,4-丁二醇为主要成分的二元醇组分通过酯化或酯交换反应和缩聚反应制备而成，其中在缩聚反应完成前加入 0.001 至 0.5 摩尔%（以酸组分为基准）的至少一种特定芳香族磺酸化合物。
