    摘要： This invention relates to a method of preparing poly(alkylene carbonate) that has a molecular weight and polymer chain structure precisely controlled by adding a chain transfer agent composed of a compound having an alcohol or carboxylic acid functional group upon alternating copolymerization of an epoxide compound and carbon dioxide using a catalyst composed of a trivalent metal complex compound synthesized from a quaternary ammonium salt-containing Salen type ligand, and to a polymer compound prepared thereby. According to this invention, the polymer compound having a star-shaped chain as well as the polymer having a linear chain can be prepared. The low-molecular-weight poly(alkylene carbonate) has an —OH terminal group and can be used alone as a coating agent, etc., and also in mixtures with an isocyanate compound and thus can be easily utilized to prepare polyurethane.

    摘要翻译： 本发明涉及一种制备聚（亚烷基碳酸酯）的方法，该聚（碳酸亚烷基酯）具有通过在环氧化合物与环氧化合物交替共聚合的情况下由具有醇或羧酸官能团的化合物组成的链转移剂， 使用由含有季铵盐的Salen型配体合成的三价金属络合物组成的催化剂和由其制备的高分子化合物。 根据本发明，可以制备具有星形链的高分子化合物以及具有直链的聚合物。 低分子量聚（碳酸亚烷基酯）具有-OH端基，可以单独使用作为涂布剂等，也可以与异氰酸酯化合物的混合物使用，因此可以容易地用于制备聚氨酯。
