Polyether Polyols Suitable For Flexible Polyurethane Foam Prepared By Co-Initiation Of Aqueous Solutions Of Solid Polyhydroxyl Initiators
view source
US Patent:

56522797, Jul 29, 1997
Filed:

Oct 21, 1996
Appl. No.:

8/734557
Inventors:

Stanley L. Hager - Crosslanes WV
James E. Knight - Exton PA
Gregory F. Helma - Exton PA
Ben J. Argento - South Charleston WV
Assignee:

ARCO Chemical Technology, L.P. - Greenville DE
International Classification:

C08G 1848
US Classification:

521175
Abstract:

Polyoxyalkylene polyether polyols suitable for preparation of flexible polyurethane foams are prepared by oxyalkylating an aqueous solution of one or more polyhydric, hydroxyl-functional solid initiators under conditions where both water as well as initiator are oxyalkylated. The polyols have calculated functionalities of between about 2. 2 and 4. 0 and hydroxyl numbers in the range of 10 to 180. The polyols may be used to prepare soft, high resiliency polyurethane flexible foams at low isocyanate indexes.
