ABSTRACT:
Incorporation of from about 0.01% to about 5% of an N-alkanoyl-N,N'-dialkyl-phenylenediamine compound (e.g. N-heptanoyl-N,N'-di-sec-butyl-para-phenylenediamine) in a flame retarded polyurethane foam formulation stabilizes the formulation against scorching as the foam is formed therefrom and also improves the indentation load deflection of the foam.
