Claims
- 1. A foam which is the reaction product of at least one polyisocyanate component and at least one polyfunctional active hydrogen component, said reaction product being formed in the presence of at least one oxynitrate compound selected from the group consisting of oxynitrate slats of metals of Group IV B of the Mendeleef periodic table.
- 2. The foam of claim 1 wherein the polyfunctional active hydrogen component is a polyether polyol.
- 3. The foam of claim 1 wherein the oxynitrate compound is zirconium oxynitrate.
- 4. The foam of claim 1 wherein the oxynitrate compound is present in a concentration of at least about 3 ppm by weight based on weight of polyfunctional active hydrogen component.
- 5. The foam of claim 1 wherein the oxynitrate compound is present in the form of particles having diameters of less than about 60 microns.
- 6. The foam of claim 1 wherein the particles have diameters of less than about 15 microns.
