| Abstract: | The correlation function and corresponding spectral density functions of the internal rotation and multiple internal rotation are deduced under the condition of the contribution of the main chain being neglected. The values of 13 C T 1 and line width of butyl side chain of poly n butyl acrylate in ionomer latex interpenetrating polymer network (Io LIPN) are measured on BRUKER MSL 400 spectrometer under normal condition. The results of data simulation show that the more the side group departs from the main chain, the faster the motion is. |
