Viscosity, definition

Now, if all these different viscosity definitions are making you depressed, then this will make you suicidal. Along comes Krae-mer and defines the intrinsic viscosity a different way, as shown in Equation 12-46. 

Now, if you ve managed to keep track of all those viscosity definitions, you re a better man than I am Gunga Din (You have to be familiar with the romantic imperialism of the books and poems of Rudyard Kipling to get this allusion.) So, we have summarized them all in Table 12-3. There are two sets of names, the ones we have used, which almost everybody else also uses, and a set devised by IUPAC, which they hoped everybody would use, but almost nobody does. Just remember that what you measure is the relative viscosity and what you want to know is the intrinsic viscosity.

DGEBF (obtained from bisphenol F) has a viscosity definitely lower than that of DGEBA but exhibits general characteristics that are close to those of DGEBA.
