MODIFYING METHOD FOR GLYCOLYSIS REACTION PRODUCT OF POLYURETHANE SCRAP |
| 摘要 |
<p>A process for converting polyurethane foam into reusable polyol composition which comprises glycolyzing the polyurethane foam to yield a glycolysis polyol product containing amines and reacting the glycolysis polyol product with an alkylene oxide in a mole ratio of <1 mole of alkylene oxide per mole of active amine hydrogen atom in the glycolysis polyol product.</p> |
