AbstractThe reaction of dimethyl sulfide (DMS) vapour with solid films of γ- and photo-oxidized polypropylene and high density polyethylene is found to involve the extensive decomposition of sec. and tert. hydroperoxide groups rather than the destruction of peracids alone as reported previously. Film of oxidized PP were extremely stable to further oxidation at 60°C after DMS exposure and also lost their ability to generate nitroxide from secondary amines. Both sec. and tert. hydroperoxide groups reacted with DMS by dual kinetics. The fast-reacting hydroperoxide groups may result from catalysis of the DMS attack by other oxidation products such as carboxylic acids.
