Coating photodegradation photooxidation rate

The exact mechanisms for the conversion of hindered amine to nitroxide are not known in these coatings. According to the treatment above, the initial rate of formation of nitroxide should be proportional to [Y00 ]. From the scheme of equation 5, the overall rate of photooxidation should also be proportional to [Y00 ]. Even though there appears to be a qualitative correlation between the initial nitroxide formation rate and the rate of degradation, the initial formation rate is hardly proportional to either K or Ke. Apparently nitroxide formation from HALS- is more complex than indicated by the simple scheme above. Compared to the excellent correlation found between photodegradation rates and photoinitiation rates in these coatings, no single parameter in the... [Pg.130]
