Figure 7.

Variations in TGA-FTIR production of CO₂, NH₃, and CH_x by the samples listed in Table 3 relative to pure PA66 and plotted as (A-1.00, see Table 3) (a) BrPS, BrPBz, ZnW and SnW controls, (b) combinations of ZnW and SnW with BrPS and BrPBz in PA66. Negative values represent a reduction in gas/volatile production, while positive values represent increases relative to the control. BrPS = brominated polystyrene; BrPBz = poly(pentabromobenzyl acrylate); SnW and ZnW = tin (II) and zinc tungstates respectively.
