Abstract
Polyurethanes are prepared from a polyol which itselve contains liquid crystalline moieties or which contains dispersed or dissolved liquid crystalline polymers. The use of this polyol is found to provide improved properties to polyurethanes, especially flexible polyurethane foams, which exhibit improved load bearing.
