TL;DR: Triphenyl phosphate and a brominated phosphate were compared as flame retardant additives for polycarbonate/ABS blends as mentioned in this paper, and the concentration of the flame retardants was varied from 6 to 14%.
Abstract: Triphenyl phosphate and a brominated phosphate were compared as flame retardant additives for polycarbonate/ABS blends. The concentration of the flame retardant was varied from 6 to 14% and the polycarbonate/ABS ratio was varied from 3/1 to 1/1. A commercial polycarbonate/ABS blend is 3/1 with about 14% triphenyl phosphate for a UL-94 V-0/5V rating. Reducing the polycarbonate or the flame retardant level gives products which do not pass UL-94 V-0/5V. Compositions containing the brominated phosphate with UL-94 V-0/5V ratings include use of 6% flame retardant or 14% flame retardant with polymer ratios down to 1/1. Cone calorimetry data show significantly longer time to ignition, lower total heat release and lower peak heat release rate for the brominated phosphate-containing resin. Mechanical properties are also given.

TL;DR: In this paper, the authors proposed a method to prepare a flame-retardant cured product having excellent wear resistance and high surface hardness by reacting a monomer or oligomer component contg. with a flame retardant in the presence of a polymn.
Abstract: PURPOSE:To prepare a flame-retardant cured product having excellent wear resistance and high surface hardness by reacting a monomer or oligomer contg. a diallyl compd. with a flame retardant in the presence of a polymn. initiator. CONSTITUTION:A flame-retardant cured product is obtd. by reacting a monomer or oligomer component contg. a diallyl compd. or a mixture of these components with a compsn. contg. a flame retardant in the presence of a polymn. initiator. Examples of the diallyl compd. are monomers and oligomers of a bisallyl carbonate of an aliph., alicyclic, or arom. dihydric alcohol, and the mixtures of these compds. The usable flame retardants include brominated flame retardants (e.g. tetrabromobisphenol), inorg. flame retardants (e.g. antimony trichloride), organophosphorus flame retardants (e.g. triphenyl phosphate), and inorg. phosphorus flame retardants (e.g. red phosphorus).
