ABSTRACT:
Reaction products of isocyanuric acid and derivatives thereof such as hydroxy-phenyl isocyanuric acid reacted with 1,2-epoxy-containing compounds such as a mixture of propylene oxide and phenyl glycidyl ether have been discovered to be effective substitutes for 4,4'-methylene-bis(2-chloroaniline) as a crosslinker in high resiliency, flexible, polyurethane foams. The crosslinkers of the present invention are not presently suspected of being carcinogenic.
