The invention provides a transparent polycarbonate composition comprising a polycarbonate resin and a mixture of flame retardants comprising (A) tris(2,4,6-tribromophenoxy)-s-triazine and (B) an aromatic sulphone sulphonate in the form of an alkali metal salt. The composition achieves a UL-94 flammability test rating of V-0 at a polycarbonate thickness equal to or less than 1.6 mm. Processes for preparing the composition are also disclosed.

Flame-retarded transparent polycarbonate compositions

Poly (pentabromobenzyl acrylate) having weight average molecular weight (Mw) in the range from 4,000 to 120,000 and polydispersity index of less than 10 as determined by high temperature gel permeation chromatography, wherein the glass transition temperature of the poly (pentabromobenzyl acrylate) is not more than 150 C.&#xb0;, the poly (pentabromobenzyl acrylate) includes chains which are terminated by an end group derived from a chain length regulator, wherein the end group is a thiol group &#x2014;SR, and wherein R, is a linear or branched alkyl group composed of not less than 8 carbon atom.
