New types of ecologically friendly polymer flame-retardant systems wer
e proposed for Nylon 6,6 and polypropylene [high temperature polymer-o
rganic char former, poly(vinyl alcohol), and silicon-inorganic system]
. These systems can act in condensed and gaseous phases. The cone calo
rimeter and LOI tests indicated the improvement of fire-retardant prop
erties for compositions of flame retardants with Nylon 6,6 and polypro
pylene in comparison with pure polymers. (C) 1998 John Wiley & Sons, I
