Abstract
High-resiliency flexible polyurethane foams having at least a 10 percent vinylic polymer or copolymer content may be rendered flame retardant by incorporating therein effective amounts of ANTIBLAZE 19, reputed to have the following structure ##STR1## wherein x is equal to 0 or 1. This compound is also synergistic with other flame-retardant compounds.
