Abstract
1-[(Diorganooxyphosphonyl)methyl]2,4- and -2,6-diamino benzenes are reacted with polyacylhalides and optionally comonomers to produce polyamides which have desirable heat and fire resistance properties. These polymers are used to form fibers and fabrics where fire and flame resistance properties are important, e.g., aircraft equipment and structures.
