    • The invention relates to a process for producing polyester polyols with secondary hydroxyl end groups, including the step of the reaction of a polyester including carboxyl end groups with an epoxide of the general formula (1): wherein R1 stands for an alkyl residue or an aryl residue and the reaction is carried out in the presence of a catalyst that includes at least one nitrogen atom per molecule. The process is distinguished in that the polyester including carboxyl end groups exhibits an acid value from ≧25 mg KOH/g to ≦400 mg KOH/g and a hydroxyl value from ≦5 mg KOH/g and in that the polyester including carboxyl end groups is produced by ≧1.03 mol to ≦1.90 mol carboxyl groups or carboxyl-group equivalents of an acid component being employed per mol hydroxyl groups of an alcohol. The polyester polyols obtained, including secondary hydroxyl end groups, can be used for the purpose of producing polyurethane polymers.
    • 本发明涉及一种生产具有仲羟基端基的聚酯多元醇的方法,包括包括羧基端基的聚酯与通式(1)的环氧化物反应的步骤:其中R1代表烷基或芳基 残基,反应在每分子包含至少一个氮原子的催化剂存在下进行。 该方法的区别在于包括羧基端基的聚酯显示出≥25mgKOH / g至≥1000的KOH值,400mg KOH / g的酸值和来自< NEE的5K KOH / g的羟值,并且包括羧基的聚酯 端基是由醇的每摩尔羟基使用的≥1.03摩尔至1升; 1.90摩尔羧基或酸组分的羧基当量。 得到的聚酯多元醇(包括仲羟基端基)可用于制备聚氨酯聚合物。
