| 摘 要： | The carbon-13 spin-spin relaxation times of fluorine-containing ionomers are measured and motional correlation times τ_o and τ_d are calculated by using VJGM model . The results show that the motions of polymer main chain in ionomers become more difficult with increasing of ionization degree and contents of functional group, and depend on the fine structures and stability of ionic microdomains.
