ADDITIVE COMPOSITION AND METHOD FOR USING THE SAME

An additive composition comprises a polyol and a zeolite composite. The zeolite composite comprises a zeolite substrate and a nitrogen-containing compound adsorbed within at least a portion of the pores in the surface of the zeolite substrate. The nitrogen-containing compound comprises (A) a first f...

Zusammenfassung:An additive composition comprises a polyol and a zeolite composite. The zeolite composite comprises a zeolite substrate and a nitrogen-containing compound adsorbed within at least a portion of the pores in the surface of the zeolite substrate. The nitrogen-containing compound comprises (A) a first functional group comprising a carbon atom doubly bonded to a nitrogen atom and (B) a second functional group comprising a hydrogen atom covalently bonded to a nitrogen atom. A method for making a polyurethane polymer comprises the steps of providing a first polyol, providing an isocyanate compound, providing an additive composition as described above, combining the first polyol, the isocyanate compound, and the additive composition to produce a reaction mixture, and reacting the isocyanate compound with the first and second polyols to produce a polyurethane polymer.
