Abstract
The internal rotations around the skeletal bonds of polyethylene are hindered due to interaction between the neighboring hydrogens. Since second and higher orders of neighborhood are not negligible, the internal rotations are interdependent. The statistics of such interdependent rotations is developed and applied to obtain the configurational partition function and the mean‐square end‐to‐end distance of the macromolecule.
