The present invention provides a novel polycarbonate diol and a polyurethane using the polycarbonate diol as raw materials. The novel polycarbonate diol produces polycarbonate diol-based polyurethane which has a high degree of hardness, superior abrasion resistance, and superior hydrophilicity, and is usable for an application such as a paint, a coating agent, a synthetic leather, an artificial leather, and a highly-functional elastomers, or the like. The present invention also provides an active-energy radiation curable polymer composition giving a cured film having a superior contamination resistance and high degree of hardness. The present invention is obtained, for example, by reacting specific two types of diols with diester carbonate in the presence of a transesterification catalyst being a compound using a metal of Group 1 or 2 on the periodic table. The present invention provides a polycarbonate diol wherein the metal content of the transesterification catalyst is 100 weight ppm or less, a polyurethane obtainable by using this polycarbonate diol and an active-energy radiation curable polymer composition containing the urethane(meth)acrylate oligomer which is obtained from the polycarbonate diol.
本发明提供了一种新型聚碳酸酯二元醇和一种以该聚碳酸酯二元醇为原料的聚氨酯。这种新型聚碳酸酯二元醇生产的聚碳酸酯二元醇基聚氨酯具有高硬度、优异的耐磨性和亲水性,可用于涂料、涂层剂、合成革、人造革和高功能弹性体等应用。本发明还提供了一种活性能量辐射固化聚合物组合物,其固化膜具有优异的抗污染性和高硬度。例如,本发明是通过使特定的两种二元醇与碳酸二酯在转酯化催化剂(使用元素周期表中第 1 或第 2 族金属的化合物)存在下发生反应而获得的。本发明提供了一种聚碳酸酯二元醇(其中酯交换催化剂的金属含量为 100 重量ppm 或更少)、一种可通过使用这种聚碳酸酯二元醇获得的聚氨酯,以及一种含有从聚碳酸酯二元醇中获得的聚氨酯(甲基)丙烯酸酯低聚物的主动能辐射固化聚合物组合物。
