摘要： A viscoelastic foam is produced by reacting (a) an isocyanate component that includes at least 25% by weight of diphenylmethane diisocyanate having a monomeric content of from 50 to 90% by weight, (b) an isocyanate-reactive component, (c) at least one catalyst, (d) at least one surface active agent, and (e) liquid carbon dioxide. These foams are characterized by a ball rebound of less than 20%. Particularly preferred foams are characterized by a 95% height recovery time greater than 4 seconds.
