Abstract

A new method for measuring the dipolar correlation function (DCF) based on the mixed magic‐ Hahn echoes decays has been implemented in inhomogeneous magnetic fields of NMR‐MOUSE®. The Hahn echo will eliminate the contribution of the linear spin interactions like the inhomogeneities of the magnetic field. Segmental order and chain dynamics were studied in a series of natural rubber sample with different cross‐link densities. The 1H residual second van Vleck moment and the correlation time were determined and correlated with the network properties.
