ABSTRACT:
Covers novel urethane-modified polyisocyanurate rigid foams comprising the reaction product obtained by bringing together in the presence of a blowing agent an aromatic polyisocyanate, an isocyanurate group formation catalyst, and a polyol comprising a specific alkylene oxide adduct of aniline. The novel foams are useful in preparing rigid foam material such as panels, slabs, or sprayed foam surfaces.
