CROSS-LINKED PHENOXYPHOSPHAZENE COMPOUND, PROCESS FOR PRODUCING THE SAME, FLAME RETARDANT, FLAME-RETARDANT RESIN COMPOSITION, AND MOLDED FLAME-RETARDANT RESIN |
摘要 |
A flame retardant which has advantages, for example, that it is halogen-free , has a high melting point, is lowly volatile, and does not impair the properties inherent in resins. The flame retardant comprises a cross-linked phenoxyphosphazene compound which is a compound obtained by cross-linking a phosphazene compound with cross-linking groups, e.g., phenylene groups, each cross-linking group being interposed between two oxygen atoms left by phenyl group elimination, and which has no free hydroxyl group (derived from the cross-linking group) in the molecule and contains phenyl groups in an amount of 50 to 99.9 % based on the total number of all the phenyl groups in the phosphazene compound.
