The shapes of H-comb polymers

Abstract

The Monte Carlo pivot algorithm is employed to investigate the shapes of continuum, tangent hard sphere H-comb polymers in both the ideal and excluded volume regimes. Polymers with a number of units ranging from 241 to 931 have been simulated. It is found that the extrapolated asphericity values are in excellent agreement with theory in the ideal regime and that, somewhat, higher values occur in the excluded volume regime.
