Abstract

Non-halogen flame retardants have been the focus of extensive research because of environmental problems. Hexakisp-henoxycyclotriphosphazene was synthesized in order to use as the flame retardant of ABS resin. And using bisphenol A, the polymers containing a cyclotriphosphazene structure were synthesized in order to also use as the flame retardant of ABS resin. All of the synthesized polymers themselves had the excellent flame retardancy. And as their molecular weight and crosslinking density were increased, the thermal stability was increased. But when the synthesized compounds were used as the flame retardant for ABS resin, the lower molecular weight compound in these compounds showed the better flame retardancy and the better physical properties of ABS resin.
