The nature of the molecular interactions occurring in an ethylene-propylene copolymer functionalized by succinic anhydride groups has been investigated by using FTi.r. spectroscopy. Hydrogen bonding interactions between carboxylic acid units and between carboxylic acid and anhydride groups have been identified. The mechanical tensile properties of such modified elastomers have been investigated and interpreted in terms of the molecular interactions detected spectroscopically. Finally, the effectiveness of these functionalized rubbers as toughening agents for polyamide-6 has also been examined.
