Popis:	Frequency responses of molecular movements of network polydimethylsiloxanes with fixed spacings between rings at the network points have been investigated by NMR. The activation energies and frequencies of segmental movements of dimethylsiloxane units have been obtained for the polymers with a great variety of spacings between network points by measuring the temperature dependences of transverse and longitudinal nuclear magnetic relaxation times.
