Title:

CROSSLINKED PHENOXYPHOSPHAZENE COMPOUNDS, FLAME RETARDANT, FLAME-RETARDANT RESIN COMPOSITIONS, AND MOLDINGS OF FLAME-RETARDANT RESINS

Document Type and Number:

WIPO Patent Application WO/1999/019383

Kind Code:

A1

Abstract:

A flame retardant which is free from halogen, has a high melting point and low volatility, and does not lower the characteristics inherent in resins, comprising a crosslinked phenoxy-phosphazene compound obtained by crosslinking a phosphazene compound with crosslinking groups such as phenylene groups, wherein each crosslinking group is interposed between the two oxygen atoms left after the elimination of phenyl groups and the amount of the phenyl groups of the crosslinked phosphazene compound is 50 to 99.9 % based on the total amount of the phenyl groups of the phosphazene compound before crosslinking. Further, the present invention also provides resin compositions containing the flame retardant; and moldings of the resin compositions.
