Abstract: Hydroxyl-containing copolymers of butylene oxide and ethylene oxide having a hydroxyl equivalent weight of at least 150, an average of 1.8 to 6 hydroxyl groups per molecule of which hydroxyl groups at least 70% are primary hydroxyl groups and an oxyethylene content of no greater than 10% by weight based on the weight of the copolymer, are useful for making polyurethanes. These polyols are characterized by high reactivity and fast curing times. Polyurethanes made using these polyols have excellent mechanical properties and are highly hydrophobic.

Abstract: A fire-resistant polyurethane composition and a fire-resistant product comprising the fire-resistant polyurethane composition. The fire-resistant polyurethane coating composition comprises: an aromatic isocyanate component, a polyol component, and an intumescent component; wherein the aromatic structure in the polyurethane backbone is ≥24 wt %. The fire-resistant polyurethane composition could provide surprisingly good intumescent layer toughness as well as good insulation performance.
