Abstract: Propylene oxide, ethylene oxide, or a propylene oxide/ethylene oxide mixture are reacted with 1,2-phenylene diamine to form adducts having hydroxyl and amino groups. The 1,2-phenylene diamine adducts are useful in making rigid polyurethane foams, especially foams for pour-in-place applications, where they give a good combination of low k-factor and short demold times. The polyols also have unexpectedly low viscosities.

Abstract: Isocyanate reactive materials of natural origin having an average isocyanate reactive functionality of less than about 1.5 can be used to enhance polyurethane foams.

While it is preferred to include at least one natural oil polyol in the polyol composition, doing so is optional.

Abstract: A process for preparing a multilayered foam article such as an automotive seat is disclosed. A mold is arranged so that the bottom surface of the mold is flat or inclined up to 40 degrees to the horizontal plane. The first liquid foam formulation designed to produce a soft foam is poured into the mold from a mixing head outlet strip-wise across the seating zone of the mold along the line parallel to but near the external wall of the seating zone of the mold. Then, the second liquid foam formulation designed to produce a hard foam is poured into the mold from the same or different mixing head outlet strip-wise across the seating zone of the mold along the line parallel to but nearer to the external wall of the mold than the line of pouring of the first liquid foam formulation. The second liquid foam formulation is then allowed to spread on top of the first liquid foam formulation, the mold is closed and the foames are allowed to rise and cure in the mold.
