Flame retardant thermoplastic compositions

摘要

A flame retardant thermoplastic polymer containing a flame retardant amount of a flame retardant additive mixture. The mixture is comprised of halogenated imide-containing polyols having the formula: <IMAGE> and the corresponding ethers having the formula: <IMAGE> wherein R is a hydrocarbon group having the valence n+2 and is selected from the group consisting of benzene groups, naphthalene groups and alicyclic hydrocarbon groups containing 5 to 10 carbon atoms, X is selected from the group consisting of bromine and chlorine, n is an integer from 1-6 and p is an integer from 2-6. The preferred flame retardant mixture is a derivative of tetrabromophthalic anhydride.
