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.

摘要： A polymer compound having a functional group containing a cyclic part with aromatic properties comprising C, H and/or C, H, X (X is a hetero atom) in the side-chain, and a number average molecular weight of 250-1,000,000. The molar optical absorption due to the cyclic part with aromatic properties of the polymer compound is lower 30% or more than the molar optical absorption due to the cyclic part with aromatic properties in a polymerizing monomer used to introduce the cyclic part with aromatic properties. As this cyclic part has an overlapping stack structure, the compound has a hypochromic effect, and if an electron donor compound or electron-accepting compound is added, a charge transfer complex is formed.
