摘要： This invention relates to novel polyol blends, a process for preparing foams with very low resistance to air flow from certain polyol blends and to the resultant foams. The polyol blends comprise one or more monofunctional polyethers having a hydroxyl number of less than 28; one or more polyether polyols having a hydroxyl number of 20 to 240 and containing at least 50% of copolymerized oxyethylene; one or more polyether polyols having a hydroxyl number of 47 to 300 and containing from 5 to 40% of copolymerized oxyethylene; and optionally, one or more polyether polyols having a hydroxyl number of 10 to 45. This process of the invention comprises reacting one or more polyisocyanates, with an isocyanate-reactive component which comprises a specific polyol blend, in the presence of at least one catalyst, at least one surfactant and at least one blowing agent.

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.
