Rouse Model Rheological Measurements and NSE

Setting the time scale, the monomeric friction coefficient is a basic quantity in all rheological measurements. This quantity is inferred indirectly in two ways  

M[ is the monomer mass, V( mon) =Vis the size of the monomer, n the number of bonds/monomer, p the polymer density, the Avogadro number, the friction coefficient related to the monomer size and ca the relaxation frequency. 

For polyethylene (PE) and PEP systematic temperature-dependent measurements in the Rouse regime were performed. Furthermore data on the temperature-dependent end-to-end chain distance (Rl) also exist. Table 3.2 displays
