Polymers as Dumbbells

More details of the rheological behavior of polymer solutions can be evaluated by representing a polymer molecule as a dumbbell that is, tv o beads connected by spring (connecting vector Q, Eigure 13.19). Their contribution to the fiuid 

When it is desired to represent a real polymer as a dumbbell, X can be estimated from the intrinsic viscosity measurement by means of Eq. (15).
