Abstract :
Cyclotriphosphazene derivatives were synthesized for use as a non-halogen flame retardant for ABS. Hexachlorocyclotriphosphazene was reacted with phenol, catechol, or 2,3-dihydroxynaphthalene, respectively, and the fire retardant ability of each product in ABS resin was characterized by UL 94 and LOI tests. The mechanical properties of ABS compounds containing one of these flame retardants were also examined. The derivative (HNCP) synthesized from 2,3-dihydroxynaphthalene showed the best flame retardance among these derivatives studied. Synergistic effects with novolac were observed in the cases using the derivative (PNCP) obtained from phenol, but little synergistic effects were observed in cases using HNCP.
