Linear Viscoelasticity Theory for Miscible Polymer Blends

1 Linear Viscoelasticity Theory for Miscible Polymer Blends 

Then the dynamics of the primitive chain 1, representing polymer 1, can be expressed in the form of the Smoluchowski equation (Riskin 1989)  

The fraction of all steps initially located at Xj which are still occupied after time t can be obtained by integrating Eq. (7.24), yielding 

Similarly, the dynamics for chain 2, representing polymer 2, can be expressed as
