A flame-retardant composition. |
摘要 |
A flame-retardant composition useful in rendering polymers flame-retardant by copolymerizing with the starting monomers, which composition comprises a halogenated, phosphorus-containing polyester obtainable by reacting a polyhydroxyphosphonic compound (A) with a halogenated polycarboxylic compound (B) in such a ratio as to provide two or more hydroxyl groups in the resulting polyester, optionally followed by the reaction thereof with a multifunctional organic compound (C), which compound (C) is reactive towards the hydroxyl groups of said halogenated, phosphorus-containing polyester.
