Abstract

Analytical methods and the Monte Carlo pivot algorithm are employed to investigate continuum, tangent hard sphere comb polymers with three and four junctions in both the ideal and excluded volume regimes. The mean-square radius of gyration, the g-ratio, and the form factor are calculated. It is found that the extrapolated Monte Carlo g-ratio values are in excellent agreement with the theory in the ideal regime. The Monte Carlo data agree well with the exact form factors. The form factors reveal the influence of the polymer structure at short distances.
