摘要：【中文】本发明涉及一种聚醚碳酸酯多元醇的制备方法，主要解决现有技术中制备聚醚碳酸酯多元醇时，采用常规无定型双金属氰化络合物催化剂的比表面积大于10㎡/g，催化剂活性低，制备得到的聚醚碳酸酯多元醇中副产物含量高的技术问题。本发明通过采用一种聚醚碳酸酯多元醇的制备方法，以低分子量的聚醚多元醇为起始剂，采用高活性无定型双金属氰化络合物为催化剂，在较低压力下，进行氧化烯烃和二氧化碳共聚反应得到聚醚碳酸酯多元醇的技术方案，较好地解决了该问题，可应用于聚醚碳酸酯多元醇的生产中。 【EN】The invention relates to a preparation method of polyether carbonate polyol, which mainly solves the technical problems that when polyether carbonate polyol is prepared in the prior art, the specific surface area of a conventional amorphous bimetallic cyanide complex catalyst is larger than 10 square meters per gram, the activity of the catalyst is low, and the content of by-products in the prepared polyether carbonate polyol is high. The invention adopts the technical scheme that polyether carbonate polyol is obtained by taking polyether polyol with low molecular weight as an initiator and taking a high-activity amorphous bimetallic cyanide complex as a catalyst and carrying out copolymerization reaction of alkylene oxide and carbon dioxide under lower pressure, thereby better solving the problem and being applicable to production of the polyether carbonate polyol.
