摘要
Three cyclotriphosphazene derivatives were used as flame retardants for ABS resin in this study. These compounds were synthesized by the reaction of hexachlorocyclotriphosphazene with 2,2'-dihydroxybiphenyl, 1,8-dihydroxynaphthalene and 9,10-dihydroxyphenanthrene respectively. The activities of these compounds as flame retardants for ABS were characterized by UL94 and LOI tests. The 9,10-dihydroxyphenanthrene derivatives showed the best flame-retardant activity. The effects of these compounds to the physical properties of ABS were also measured. The synergistic effect of antimony (V) oxide or novolac to these flame retardant compounds were discussed.
