A new method of quantitative determination of interfacial copolymers was investigated. Because of the small amount of these copolymers, the measurement is hard and only one technique is available: photoelectron X spectroscopy (XPS). However, as the method is an atomic response, it cannot be executed to any materials: copolymers have to contain different atom from the bulk. In this paper, we show that titration of interfacial copolymers polyamide 6-co-polypropylene-grafted anhydrid maleic (PA6-co-PP-g-AM) can also be done by Fourier Transform Infrared (FTIR). Concerning the quantitative determination of ethylene vinyl alcohol-polypropylene-grafted anhydrid maleic interfacial copolymers (EVOH-co-PP-g-AM), nothing is reported in literature. We show here, that FTIR can measure surface density of those copolymers provided that alcohol functions of EVOH are modified to ester groups. © 2017 Elsevier B.V.
