ABSTRACT:
This invention is concerned with the employment of a water-soluble initiator, of sucrose, sorbitiol, trimethylpropane, ammonia or amine and water to form an initiator which is mixed and reacted with alkylene oxide in the presence of water and without the use of an added catalyst to produce polyether polyols for use in the production of urethane foams.
