Abstract
The NMR relaxation of the transverse magnetization of the protons attached to the polymeric chains was observed for the molten polybutadiene and for some polybutadiene–toluene solutions in a large temperature domain. The superposition properties of the relaxation curves, the linear temperature dependence of the experimental parameter t0.6(T) and the observation of the pseudo-solid echoes were correlated to the existence of the temporary junctions between the polymeric chains.
