Stabilisers are usually determined by a time-consuming extraction from the polymer, followed by an IR or UV spectrophotometric measurement on the extract. Most stabilisers are complex aromatic compounds which exhibit intense UV absorption and therefore should show luminescence in many cases. The fluorescence emission spectra of Irgafos 168 and its phosphate degradation product, recorded in hexane at an excitation wavelength of 270 nm, are not spectrally distinct. However, the fluorescence quantum yield of the phosphate greatly exceeds that of the phosphite and this difference may enable quantitation of the phosphate concentration [150]. The application of emission spectroscopy to additive analysis was illustrated for Nonox Cl (/V./V -di-/i-naphthyl-p-phcnylene-diamine) [149] with fluorescence ex/em peaks at 392/490 nm and phosphorescence ex/em at 382/516 nm. Parker and Barnes [151] have reported the use of fluorescence for the determination of V-phenyl-l-naphthylamine and N-phenyl-2-naphthylamine in extracted vulcanised rubber. While pine tar and other additives in the rubber seriously interfered with the absorption spectrophotometric method this was not the case with the fluoromet-ric method.

In another case,l l PFA (with a melt flow rate of 4-9 g/lO-min) was first mixed with 0.1% by weight of a tin powder, 0.03% by weight of N-phenyl-a-naphthylamine, and 0.02% by weight of carbon black. This mixture was tumbled in a drum while being heated to a temperature of 304°C-310°C which lightened the color of the mixture. The cooled powder was loaded in the cavity of a carousel-type rotolining machine. Tin helped eliminate the bubbles from the part.

The antiozonants, N-(l,3-di-methylbutyl)-N -phenyl-p-phenylenediamine (6PPD) and the C7 and C5 alkyl-analogs were later introduced. In addition to their nse as antiozonants, p-phenylenediamines, primarily the more persistent mixed diaryl-derivatives, have replaced N-phenyl- 3-naphthylamine as antioxidants flex crack inhibitors and synthetic polymer antioxidant stabilizers. 

The following fluorescent probes were chosen as substrates N-phenyl-1-naphthylamine (PNA), 1-benzyl-1,4-dihydronicotinamide (BNAH), indole, indolyl-Sracetic acid, 8-anilinonaphthalene-l-sulfonate (ANS), 6-p-toluidinylnaphthalene-2-sulfonate (TNS), and l-dimethylaminonaphthalene-5-sulfonamidoethyltrimethylammonium (DASP).
