Solid state NMR, based on both structural and dynamical approaches, was used to follow the curing process and thermal ageing of EPDM elastomer. The methods, including standard wideline and high resolution experiments, as well as two dimensional WISE (Wideline Separation experiment), were shown to be sensitive to chemical changes of a few tenths of a percent of the carbon content.
