ABSTRACT:
Disclosed are active hydrogen compositions comprising: (A) an organic polyol having a molecular weight of from about 100 to about 4,000 wherein at least about 40 percent of the available hydroxyl groups are primary; and (B) from about 0.5 to about 10 pph of (A) of a polyamide formed from the reaction of a C.sub.2 to C.sub.30 aliphatic monocarboxylic acid and a relatively high molecular weight amine terminated polyether.
Also disclosed are the molded polyisocyanurate polymers prepared from the above compositions and organic polyisocyanates.
