: Unique to cross-linked polymers, this is an entropic force—stretching a chain reduces its entropy, so the chain "pulls back" to return to a more disordered state. 3. Dynamics and Rheology

: The simplest model (like a Random Walk ) assumes monomers have no volume and do not interact except through their immediate neighbors. Polymer Physics

The movement of polymers is hindered by their length and surroundings. : Unique to cross-linked polymers, this is an
