摘要:
The present invention is a polyoxyalkylene polyol, its manufacture method, and derivatives, wherein: it is obtained using a phosphazenium compound as a catalyst; the hydroxyl value is 2˜200 mgKOH/g; total degree of unsaturation is 0.0001˜0.07 meq./g; the head-to-tail bond selectivity of the polyoxyalkylene polyol is 95 mole %; and when the maximum height of the peak of GPC elution curve is set to be 100%, W20 is defined as the peak width at the 20% peak height, and W80 is defined as the peak width at 80% peak height, the ratio of W20/W80 is 1.5 or greater, and less than 3.
