Abstract
⺠An NMR method for polydispersity determination of linear polymers is presented. ⺠It is based on differential diffusion observed for main chain and extremity signals. ⺠A statistical analysis of the DOSY spectrum provides an accurate estimates of PDI. ⺠The Flory coefficient of the polymer chain has to be known. ⺠Results on PEO reveal a very good accuracy.
