I.r. spectroscopic analysis, in particular by means of the technique of attenuated total reflection, is used to characterize the grafting of polypropylene (PP) films by poly(acrylic acid). A method allowing us to separate the grafted part from that of unmodified PP is also used. Finally, we compare the results obtained when the film to be modified is initially treated or not to eliminate some of the additives present. We show that whatever the case, the grafting always starts from the interface between the PP and the polymerization solvent. Therefore, grafting in all the material can be easily obtained when the additives are extracted
