| description | Rigid cellular foams characterized by carbodiimide linkages exhibit low friability and excellent flame retardancy when prepared from isocyanates rich in toluene diisocyanate. The forms hereof are prepared by the catalytic condensation of the isocyanates by using either (1) isocyanate quasi-prepolymers or (2) a two-stage process wherein isocyanate and polyol are first reacted to form a urethane-containing intermediate having free isocyanate groups and then the remaining isocyanate groups are converted to carbodiimide groups and isocyanurate groups by the catalytic condensation thereof. |
