摘要 |
<p>Disclosed is branched poly(trimethylene ether) polyols prepared from the acid catalyzed polycondensation reaction of 1,3-propanediol, and at least one triol comonomer selected from 1,1,1-tris(hydroxymethyl) ethane and 1,1,1-tris(hydroxymethyl) propane. Also disclosed is a branched poly(trimethylene ether) polyol with an equivalent hydroxyl functionality of about 2.1 to about 3.2 and a Mn of about 200 to about 6000. The polyols are useful in the preparation of polyurethane rigid and flexible foams.</p> |
