POLYOXYALKYLENEPOLYOLS, DERIVATIVES THEREOF, AND PROCESS FOR PRODUCING THE POLYOXYALKYLENEPOLYOLS

Document Type and Number:

WIPO Patent Application WO/1998/054241

Kind Code:

A1

Abstract:

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 W�20?/W�80? of at least 1.5 and below 3 (wherein the maximum height of the peak in the GPC elusion curve is 100 %, W�20? is defined to be a peak width at a height of 200 % thereof and W�80? is defined to be a peak width at a height of 80 % thereof); a process for producing them; and derivatives of them.
