ABSTRACT:
The present invention relates to polymeric hydroxylated polyesterethers and the use of such compounds in preparing polyurethane flexible foam. The hydroxylated polyesterethers are prepared from p-dioxanone, polycarboxylic acids and polyols. These polymeric hydroxylated polyesterethers can then be reacted with polyisocyanates to produce a flexible, foamed polyurethane.
