    摘要: There is described an isocyanate-based polymer foam having improved anti-yellowing properties. The foam produced from a formulation comprising an isocyanate, a blowing agent, a first active hydrogen-containing compound and a second active hydrogen-containing compound different than the first active hydrogen-containing compound. The second active hydrogen-containing compound comprises an active hydrogen-containing phosphite compound. A process for producing such a foam is also described.
