FLEXIBLE POLYUREA OR POLYUREA-POLYURETHANE FOAMS PREPARED FROM HIGH EQUIVALENT WEIGHT AMINE-TERMINATED COMPOUNDS AND PROCESS FOR PREPARING THE SAME |
摘要 |
Flexible polyurethane foams are prepared by reacting a polyisocyanate with certain amine-terminated compounds. The amine terminated compounds are characterized in having at least 30 percent of their active hydrogen-containing groups in the form of primary aromatic, Lewis acid-blocked primary aliphatic and/or secondary aromatic or aliphatic amine groups. The resulting foams exhibit excellent physical properties, even in the absence of a cross-linker compound.
