摘要
Two different types of high resolution solid-state C-13-H-1 cross depolarization experiments were applied to a rubber toughened thermoset polymer. A polypropylene blend was examined using a solid-echo H-1 wide line pulse sequence over the temperature range from 27 to 197-degrees-C. The frequency domain spectra were curve fitted to obtain the relative abundances of the three distinct H-1 T2 components as a function of temperature.
