“…High molecular weight halogenated polymers can also be used as fire retardants. 19 It is worthwhile to point out the difference between a "flame retardant" and a "fire retardant." According to Sanders,20,21 a flame-retardant chemical enables a material to resist burning when exposed to a relatively low-energy source such as a cigarette, match flame, candle flame, etc.…”

Halogenation and addition of some heavy metallic oxides have been in use for a few decades to impart flame-retarding properties to polymers. In this study bromine was added to the polymer (polyester of propylene glycol ϩ phthalic anhydride) by means of decabromodiphenyloxide (DBDPO) at varying concentrations. In addition to bromine, 2% antimony oxide (Sb 2 O 3 ) was also added. In predicting the flameretarding properties of the polymeric samples prepared, the oxygen index test and the burning rate tests were applied. The results of these tests indicate that the oxygen index values of brominated polyester increase linearly as bromine content increases, and that the polyester containing 2% Sb 2 O 3 in addition to 10 -12% Br has a marked flame-retarding property. The mechanical properties were also studied, and some improvement has been observed in mechanical properties by adding acrylonitrile to the polyester.

Imparting thermal stability to polymethyl methacrylate (PMMA) without affecting its optical clarity is attempted by incorporating HET acid based oligoesters. Pure PMMA and PMMA containing five and 20 wt% of four different oligoesters are separately prepared using bulk polymerization. The thermal properties of the materials studied using DSC, TG, TG-FTIR and Pyr-GC-MS are presented. The main volatile degradation products identified are CO, HCl, CO2, H2O, hexachlorocyclopentadiene, hexachloroendomethylene tetrahydrophthalic acid/anhydride and methyl methacrylate. A detailed mechanism for the influence of the degradation products of HET acid based oligoesters on the thermal degradation of PMMA is also presented.
