✦ Synopsis

The initial transformation products from nickel dialkyl dithiophosphates and nickel alkyl xanthates have been identified by spectrophotometric and kinetic methods. A common mechanism of action is involved for both nickel complexes and the distribution of products from complexes during their reaction with hydroperoxides suggests a greater contribution from an ionic mechanism in the case of dithiophosphate. Nickel dialkyl dithiophosphate is more stable to u.v. light than nickel alkyl xanthate and its reaction with tert. butyl hydroperoxide in the presence and absence of light is 7-8 times fllster than that of the xanthate.

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
