Abstract:
A process for the preparation of a polyether polyol having a functionality of at least about 3, a molecular weight of from about 560 to about 35,000 and an OH number of from about 10 to about 1,100, comprising(1) reacting (a) a polyether polyol containing one or more ether groups, having a functionality of about 2 to about 8, a molecular weight of about 106 to about 12,000, and an OH number of about 28 to about 1,400, with (b) cyanuric chloride optionally, in the presence of (c) one or more catalysts; wherein the functionality of the resultant polyether polyol equals three times the functionality of (a) said polyether polyol minus three.
