Patent

CA 2307997

An isocyanate-reactive composition containing a blowing agent that is generally a gas at ambient temperature and pressure which is storage stable is produced by including a phenol or alkylphenol having at least one phenolic hydroxyl group in the isocyanate-reactive composition in an amount sufficient to promote the solubility of the blowing agent. The isocyanate-reactive composition may be stored at ambient conditions rather than under pressure. The isocyanate-reactive composition containing blowing agent may be used to produce foams having good physical properties after storage at ambient temperature and pressure for periods as long as 3 months.
