Monte Carlo Studies of the Relaxation of Vector End-to-End Length in Random-Coil Polymer Chains

Abstract

The effects of excluded volume interactions upon the dynamical behavior of random‐coil polymer chains are studied by obtaining autocorrelation functions for vector end‐to‐end length of lattice‐model chains of 9, 15, 33, and 63 beads by a Monte Carlo simulation technique. It is found that relaxation of the vector end‐to‐end length requires from 4 to 7 times as long as relaxation of its square, in contrast to the predictions of simple models without excluded volume effects.
