摘要：

Curing and thermal ageing of EPDM synthetic elastomers has been studied using both C-13 high-resolution and H-1 wideline solid-state NMR experiments based on structural and dynamic parameter measurements. It is shown that cross-linking, scission and oxidation reactions can be clearly identified and quantified at concentrations as low as a few tenths percent of the carbon content. The feasibility and efficiency of two-dimensional WISE experiment for studying ageing of heterogeneous polymer-based systems has been demonstrated providing unique chemical specific dynamic information.
