Pulsed Nuclear Magnetic Resonance measurement is presented for three series of the block polymer of styrene and isoprene. The solid echo measurement was made on a Bruker MSL-300 NMR Spectrometer operating at 300 MHz. The solid echo signals were decomposed by means
of linear least square regression into a fast Gaussian and a slow exponential components associated with the rigid and mobile phase respectively
using PASCAL language and lealed with on the Aspect-3000 computer which is equipped on the spectromeeter. The qualitative and quan-titative informations of the phase structure and molecular motion can be obtained by means of this method.
