Abstract
Copolyesters containing secondary hydroxyl groups are useful polyols for manufacturing polyurethanes. These can be prepared by reacting a secondary hydroxyl-containing fatty acid or ester thereof with an initiator containing hydroxyl and/or primary or secondary amino groups. A copolyester of particular interest includes a poly(ethylene oxide) segment derived from a poly(ethylene oxide) initiator.
