    摘要： A novel polycarbonate diol is useful as a raw material for producing a polycarbonate diol-based polyurethane with a high degree of hardness, superior abrasion resistance, and superior hydrophilicity. The polyurethane is useful in paints, coating agents, synthetic leathers, artificial leathers, and highly-functional elastomers, or the like. The polycarbonate diol is also useful for producing an active-energy radiation curable polymer composition giving a cured film having superior contamination resistance and high degree of hardness. The curable polymer composition contains a urethane(meth)acrylate oligomer obtained from the polycarbonate diol. The polycarbonate diol is obtained, for example, by reacting two specific types of diols with diester carbonate in the presence of a transesterification catalyst. The catalyst has a metal of Group 1 or 2 on the periodic table. A metal content of the transesterification catalyst is 100 weight ppm or less.

    摘要翻译： 新型聚碳酸酯二醇作为制造硬度高，耐磨耗性优异，亲水性优异的聚碳酸酯二醇类聚氨酯的原料是有用的。 聚氨酯可用于涂料，包衣剂，合成皮革，人造皮革和高功能弹性体等。 聚碳酸酯二醇也可用于生产具有优异的耐污染性和高硬度的固化膜的活性能量辐射固化聚合物组合物。 可固化聚合物组合物含有由聚碳酸酯二醇得到的氨基甲酸酯（甲基）丙烯酸酯低聚物。 聚碳酸酯二醇例如通过在酯交换催化剂的存在下使两种特定类型的二醇与二酯碳酸酯反应而获得。 催化剂在周期表上具有1或2族的金属。 酯交换催化剂的金属含量为100重量ppm以下。
