3-Quinuclidinol catalyst compositions for making polyurethane foams. |
摘要 |
<p>A method for preparing a polyurethane foam which comprises reacting an organic polyisocyanate and a polyol in the presence of a blowing agent, a cell stabilizer and a catalyst composition consisting essentially of at least one compound of the following formula: <CHEM> where R is hydrogen, C1-C8 alkyl, C6-C10 aryl or C7-C10 aralkyl, and n is 0-3. The preferred catalyst consists essentially of of the compound when n is 0, namely 3-quinuclidinol.</p> |
