A halogen-containing polyether polyol having a low content of unsaturated components, and a polyurethane using the same. A halogen-containing polyether polyol represented by the formula (1) having a molecular weight of 200 to 100,000 and an unsaturation level of 0.02 meq / g or less, and a polyurethane using the same. (Q is a polymer component containing a cyclic ether structural unit by ring opening of epihalohydrin; m is an integer of 2 to 8; R 1 is an active hydrogen-containing compound residue) [Selection figure] None |
