Lecture 16

The document compares the characteristics of real polymer chains with the Kuhn model. It highlights differences in bond angles, torsional constraints, segment correlation, excluded volume, and mathematical tractability. The Kuhn model simplifies these features for easier analysis by averaging or ignoring complexities present in real polymers.

Lecture-16

1st April 2025

Kuhn Model:

Feature Real Polymer Chain Kuhn Model


Bond angles, stiffness Present, often complex Averaged out
Torsional constraints Present Ignored
Segment correlation Often present over short distances None (segments are independent)
Excluded volume Often significant Ignored (ideal chain assumption)
Mathematical tractability Hard Simple (Gaussian statistics)
