PROCEDE DE PREPARATION D'UN POLYMERE CELLULAIRE DERIVE D'ISOCYANATE ET PRODUIT OBTENU |
| 摘要 |
Active hydrogen-containing fluorochemical is used as a foam stabilizer for foamed isocyanate-derived polymers. For example, rigid or flexible polyurethane foams with high or low density and uniform cellular structure are prepared using fluoroaliphatic radical-substituted polyamines as foam stabilizers. |
