Abstraet--A new method is described for the evaluation of antioxidants for polypropylene by torsional braid analysis. This technique shows the dominating influence of antioxidant volatility on the lifetime of articles with a high surface area to volume ratio (e.g. fibres and films).
lsopropylaminodiphenylamine (IPPD, I) and a hindered bispiperidine ella) are effective antifatigue agents in vulcanized rubber. The former is also a powerful thermal antioxidant and antiozonant whereas the latter is not. An investigation of the mechanism of antifatigue action shows that both I and i
