Abstract
Polyether diols characterized by a hydroxyl number of 56 or lower, high average functionality and high primary hydroxyl content are prepared by alkoxylating an unsaturated alcohol in multiple steps to form a polyether monol that contains 39% or more primary hydroxyl groups, and then reacting the polyether monol with a mercaptoalcohol that has a primary hydroxyl group.
