<p>Polyoxyalkylenepolyols obtained by using a phosphazenium compound as the catalyst and having a hydroxyl value of 2 to 200 mgKOH/g, a total unsaturation of 0.0001 to 0.07 meq./g, a head-to-tail bond selectivity toward polyoxypropylenepolyols of 95 molar % or higher, and W20/W80 of at least 1.5 and below 3 (wherein the maximum height of the peak in the GPC elusion curve is 100 %, W20 is defined to be a peak width at a height of 200 % thereof and W80 is defined to be a peak width at a height of 80 % thereof); a process for producing them; and derivatives of them.</p> |
