Popis: The effects of solvent extraction of increasing severity on carbon black filled natural rubber are examined. Collated NMR, DSC, and DMTA methods examine the glass transition and motional cooperation in the filled system. DSC is insensitive to the immobilization of small amounts of tightly bound rubber on the surface of carbon black particles. Also examination of component T 2 intensity data as a function of temperature engenders the notion of a range of binding energies between the rubber and the carbon black. The Carr-Purcell pulse train has been used to glean additional insight into the dynamics of molecular motion, and exchange between heterogeneous sites is explored
