摘要: Hydroperoxide products in solid oxidized polyolefins have been measured by iodometry, Fe2+ reaction and derivatization infrared spectroscopy methods. Polyethylene, polypropylene elastomers were photo, thermal γ-initiation. The traditional iodometric method appears to be highly reliable within certain constraints of time imposed sample crosslinking. was found give values consistently one order magnitude below the true level because failure reagents penetrate into polymers even after a prior swelling step. Derivatization hydroperoxides with nitric oxide produced nitrates which could high sensitivity. Total nitrate yields agreed well determination hydroperoxide for conditions under stable. Different nitrates, hence hydroperoxides, identified quantified this method.
