ABSTRACT:
Flexible cellular foam compositions are prepared by reacting in the presence of water an organic compound having at least two active hydrogen atoms with an organic polyisocyanate employing an isocyanate index of from about 130 to about 225 in the presence of a catalytically sufficient amount of certain isocyanate trimerization catalysts. The resulting foam compositions exhibit excellent flame retardant properties.
