Abstract
A series of hydroxy-terminated amides has been discovered. They are of the formulae: R--[NHCO(CH.sub.2).sub.z OH].sub.2 and R--[NHCO(CH.sub.2 OCH.sub.2 OCH.sub.2 CH.sub.2 OH)].sub.2 wherein: R is a polyoxyethylene radical of 1 to 9 mers which is optionally capped at both ends with 1 or 2 propylene oxide mers, and z is 3 or 5. The amides are water soluble and cold acetone insoluble. They are useful in flexible polyurethane foams.
