ABSTRACT
At the same time, gas chromatographic analysis (44) showed that dialkylsulfide injection into oxidized PP causes a significant increase of ethylene yield, which indicates a sulfide interaction with polymer peroxyls. Entering the co-oxidation with PP, dialkylsulfides cause no significant increase in the induction period. However, in the presence of a "weak" phenol, they are able to increase the induction period
significantly, displaying synergism. The mechanism of this phenomenon may be shown, if we take into account that dialkylsulfides interact with peroxyls (44). Because of this interaction, the decrease of peroxyl concentration occurs, which induces the chain expenditure of alkylphenol.
