ABSTRACT This invention relates to alkylene oxide adducts having an average hydroxyl equivalent weight of from 800 to 3000 and containing up to 20 weight percent polymerized ethylene oxide. The adducts are prepared by alkoxylating an initiator containing from 5 to 50 weight percent polymerized ethylene oxide, with a C3 or higher alkylene oxide. The invention offers the advantage of preparing alkylene oxide adducts and polyurethane foams therefrom with acceptable properties, where the availability or the possibility of conducting an alkoxylation reaction with ethylene oxide is restricted or not at all feasible. 32,086-F
