CO2 CONTAINING FOAMS AND RELATED METHODS |
| 摘要 |
The present invention provides methods for producing polyurethane foam compositions. Such methods include mixing an A-side composition, a B-side composition, and CO2 to provide a foam mixture, wherein at least a portion of the CO2 is added as a separate stream, or is provided dissolved in the B-side composition. |

1. A method for producing a polyurethane foam composition, the method comprising the steps of
providing an A-side composition comprising one or more polyisocyanates; providing a B-side composition comprising one or more highly alternating polycarbonate polyols derived from the copolymerization of one or more epoxides and CO2; heating the B-side composition to an elevated temperature; mixing the A-side composition, the heated B-side composition, and CO2 to provide a foam mixture; and allowing the foam mixture to cure into the polyurethane foam composition; wherein at least a portion of the CO2 is added as a separate stream, or is provided dissolved in the B-side composition. |
