Abstract: Production of isocyanate-based rigid foam by reacting polyisocyanates with compounds having at least 2 isocyanate-reactive hydrogen atoms, at least one of which is a polyester alcohol, comprises (A) reacting a polyester alcohol or a polyol mixture containing polyester alcohol(s) with less than the stoichiometric amount of at least difunctional isocyanate(s) to a prepolymer (I) containing urethane and hydroxyl groups, (B) reacting (I) with polyisocyanate. Independent claims are also included for the following: (1) (I) with a hydroxyl (OH) number in the 100-400 mg KOH/g range; (2) rigid isocyanate-based foams produced by this process.
