ABSTRACT:
Polyurethane foams are prepared by reacting a polyisocyanate and a polyahl in the presence of water and a dialkanol tertiary amine. The foams are rigid, useful for thermal insulation in roofs, walls, refrigerators, etc., and are capable of filling mold space completely on foaming (good flowability) without shrinking excessively.
