Patent Searching and Data


Document Type and Number:
Japanese Patent JPS5176394
Kind Code:
A
Abstract:
Acid-modified toluene diisocyanate is used to prepare rigid cellular foams characterized by carbodiimide linkages either by a one-shot process or a quasi-prepolymer process. The use of acid-modified toluene diisocyanate exhibits a more controllable reactivity with a one-shot foaming process and more stable quasi-prepolymers when using such systems.
