    摘要: A method for preparing a polyether polyol copolymer includes the step of copolymerizing (1) a cyclic ether represented by the following formula (I): 1 wherein x is an integer ranging from 2 to 10; (2) a diol represented by the following formula (II): HOnull(CH2)xnullOHnullnull(II)wherein x is the same as that specified above; and (3) other polyols, in the presence of an acid catalyst. The method permits the arbitrary modification of the content of the O(CH2)x units present in the main chain of a polyether polyol copolymer so that the copolymer may have an appropriate crystallinity suitable for use as an elastomer by controlling the ratio of the diol represented by Formula (II) used in the copolymerization and simultaneously permits the change of the molecular weight of the resulting polyether polyol copolymer.
