Abstract

The relaxation of the transverse magnetization of the protons attached to the polymeric chains and the pseudo-solid echoes were observed for the molten polybutadiene by NMR method. The function that characterizes the fluctuations of the polymeric segments can be estimated from the analysis of the experimental data collected in a large temperature domain..

Keywords
