Based on pulse radiolysis of aqueous solutions of four pheriolic antioxidants including green tea polyphenols, quercetin, caffeic acid and sinapic acid the rate constants for reactions of OH and the antioxidants were determined. And green tea polyphenols and quercetin are the strongest antioxidants.
Abstrac~A study has been carried out on the loss of mononuclear phenolic antioxidants from polypropylene under conditions which simulate those found both during the incorporation of the antioxidant into the polymer at 190[ and during subsequent usage at 140 Β°. In the latter case, rate constans have
