Most of the work on the inhibition of oxidative degradation of HTPB by incorporating anti-oxidants is in the form of patents or classified reports [225-227]. The use of N-phenyl-P-naphthylamine (PBNA) has been extensively studied [226, 228] for this purpose but it is reported to be a carcinogenic material and hence banned for use as a propellant ingredient in developed countries.

The quantum yields decreases by changing from planar naphtholes to the perpendicular binaphthole independent on the absence or presence of pyridine [162], Also, in the case of optical active l,T-binaphthyl-2,2 -diamine (BNA) compared with A-phenyl-p-naphthylamine (PNA), the quantum yield of electron transfer is for BNA by a factor of 0.5 lower due to the perpendicular structure [161]. A possible explanation is that the approach of the perpendicular donors BN(OH)2 and BNA to the almost spherical fullerenes is hindered, while the planar 2-NOH and PNA more easily contact with the fullerenes [161,162], The quantum yields of C70 in the absence of pyridine are slightly higher than those of C6o suggesting a slightly stronger acceptor ability of C70 [162],...

Also, antioxidants were found to decrease the aging rate of natural rubber. Among the antioxidants more frequently used are N-phenyl-p-naphthylamine, 2,6-di-tert-butyl-4-methyl-1-hydroxybenzene (BHT), N-isopropyl-N -phenyl-p-phenylenediamine, N-(1,3-dimethylbutyl)-N -p-phenylenediamine, and poly-(2,2,4-trimethyl-1,2-dihydroquinoline). 

Amongst heat stabilisers are copper salts, phosphoric acid esters, phenyl-P-naphthylamine, mercaptobenzothiazole and mercaptobenzimidazole. Of these, copper salts in conjunction with halides have been found particularly effective, and some automotive specifications require the use of copper for heat stabilisation. Light stabilisers include carbon black and various phenolic materials. 

Apart from the alkylated phenols, phenyl-p-naphthylamine, acetone diphe-nylamine reaction products and alkylated diphenylamines are also used in different industrial applications and they can absorb UV light. Using proper solvents, these antioxidants can be both qualitatively and quantitatively analysed. Table 5.1 shows the solvents and test conditions for determination of antioxidants. ... 

N,N, P - phenylcyclohexil - p - phenylene diamine N,N, P - diphenyl - p - phenylene diamine and phenyl - P - naphthylamine conserve strength of PA - fibres by 70-95% at it warming up for 2 hours at 200 ° C (unstabilized fibre - 22%). Despite high inhibitive activity their use is limited, as intermediate products of their transformations dye polymer. 

Anti-oxidants, AOs, for ester-based turbine lubricants are of the hindered amine type, as described in Chapter 4. Commonly used anti-oxidants are phenyl-a-naphthylamine, PAN, octylphenyl-a-naphthylamine, ORAN, and dioctyldipheny-lamine, DODPA, and derivatives thereof. Phenothiazine was a common anti-oxidant in the early years of ester-based turbine lubricants but although effective it formed particulates when the lubricant became oxidised. Since particulate formation is a major limiting factor for an engine manufacturer the use of phenothiazine stopped. Phenyl-P-naphthylamine was also used in early lubricants but its use was subsequently banned when it was found to be harmful.
