TLDR
In this paper, it has been found that the use of a certain type of flame-retardants, namely oligomeric phosphates, leads to a polymer mixture having improved properties.
Abstract: 
The invention relates to a polymer mixture which comprises an aromatic polycarbonate, a styrene-containing copolymer and/or a styrene-containing graft polymer and a flame-retardant. It has been found that the use of a certain type of flame-retardants, namely oligomeric phosphates leads to a polymer mixture having improved properties. In particular to a polymer mixture having a good combination of flame retardancy, non-juicing characteristics of the flame retardant, good plastifying effect and good heat resistance.

Flame retardant aromatic polycarbonate with good mechanical properties and melt stability

Gerard E. Reinert
TL;DR: In this article, a flame retardant polycarbonate composition having good mechanical properties and melt stability was proposed. But the properties were achieved by adding small amounts of a fibril forming polytetrafluoroethylene, and an alkali metal salt of an inorganic acid, and a small amount of aromatically bound chlorine or bromine contained in a compound other than an organic alkaline metal or alkaline earth metal salt to a thermoplastic aromatic poly carbonate.
