Normalized molecular weight relaxation-time ratios

The fact that these two relaxation-time ratios are a universal function of M/Mg indicates that the universality of the G t) line shape extends to the PA t) process region, pxit) is situated between pA t) and the processes PB t) and pc t)- Thus, although we do not have the theoretical form for Px t), its characteristic time tx normalized with respect to should also be a function of the normalized molecular weight M/Mg- From the G t) line shape analysis in terms of Eq. (9.19) as discussed in detail in Chapter 10, it has been found that tx is best described by...
