Hydrophobic polyols

A polyurethane glass sealant is made by reacting a poly(1,2-butylene oxide) polymer with a chain extender and a polyisocyanate. The poly(1,2-butylene oxide) polymer may be used as a mixture with up to 50% by weight of other polyols, including castor oil. The sealant is especially useful as a secondary sealant for an insulated glass unit (IGU).
