Abstract
Threo- anderythro-9,10-dihydroxystearic acids were reacted with 2, 4, 6 and 8 moles of ethylene oxide. The oxyethylated polyols from thethreo acid, adjusted to equivalent weight 100 with triisopropanolamine, were converted to satisfactory rigid foams by mixing with corresponding amts of isocyanate-terminated oxypropylated sorbitol prepolymers of three viscosities. Typical foam properties had maxima for the tetra- or hexaoxyethylene polyol, and most properties paralleled prepolymer viscosity.
