Abstract: The investigation was carried out on the influence of the addition of a small amount of lignin or its derivatives on the reaction of polypropylene crosslinking initiated by peroxides. Thermooxidation stability of the crosslinked samples was also studied. Unmodified oak lignin is the only additive affecting the crosslinking process significantly. The increase of thermooxidation stability was observed in samples containing lignin or most of its derivatives but the effect was small.
