    • The invention is a high molecular weight polyether polyol prepared by the reaction of one or more compounds having one or more active hydrogen compounds with one or more alkylene oxides in the presence of a catalyst comprising calcium having counterions of carbonate and a C6-10 alkanoate in a solvent or dispersant which does not contain active hydrogen atoms. The polyether polyol prepared preferably has an equivalent weight of from about 1000 to about 20,000, a polydispersity of 1.3 or less and a residual catalyst level of from about 0 to about 2000 parts per million (ppm). In another embodiment the invention is a process for preparing such high molecular weight polyether polyols. The process comprises first, contacting one or more compounds having one or more active hydrogen atoms with one or more alkylene oxides in the presence of a catalyst. The catalyst comprises calcium having counterions of carbonate and a C6-10 alkanoate in a solvent, wherein the solvent does not contain active hydrogen atoms. The mixture is exposed to conditions at which the alkylene oxides react with the compound containing more than one active hydrogen atoms such that a polyether polyol is prepared which has an equivalent weight of from about 1,000 to about 20,000, a polydispersity of about 1.3 or less and a residual catalyst level of from about 0 to about 1000 (ppm).
    • 本发明是一种高分子量聚醚多元醇,其通过一种或多种具有一种或多种活性氢化合物与一种或多种烯化氧的化合物的反应制备,所述化合物在催化剂存在下,该催化剂包含具有与碳酸酯和C 6-10链烷酸酯的抗衡离子的钙 不含活性氢原子的溶剂或分散剂。 制备的聚醚多元醇的当量重量优选为约1000至约20,000,多分散性为1.3或更低,残留催化剂含量为约0至约2000ppm(ppm)。 在另一个实施方案中,本发明是制备这种高分子量聚醚多元醇的方法。 该方法首先在催化剂存在下使具有一个或多个活性氢原子的一种或多种化合物与一种或多种环氧烷接触。 该催化剂包括在溶剂中具有碳酸酯和C 6-10链烷酸酯的抗衡离子的钙,其中溶剂不含活性氢原子。 将混合物暴露于环氧烷与含有多于一个活性氢原子的化合物反应的条件,使得制备的聚醚多元醇的当量为约1,000至约20,000,多分散度为约1.3或更小,以及 残余催化剂水平为约0至约1000(ppm)。
