Two different types of high resolution solid‐state 13 C‐ 1 H cross depolarization experiments were applied to a rubber toughened thermoset polymer. A polypropylene blend was examined using a solid‐echo 1 H wide line pulse sequence over the temperature range from 27 to 197°C. The frequency domain spectra were curve fitted to obtain the relative abundances of the three distinct 1 H T 2 components as a function of temperature.
