Abstract
Brownian dynamics simulations are made for continuum, excluded, and nonexcluded volume, uniform H‐comb polymers in two dimensions. It is found that the end‐to‐end distance and radius of gyration of the inner branches are expanded more than those of the outer branches for excluded volume combs. The ratio of the end‐to‐end distance scaling amplitudes appears to be a universal quantity in agreement with the conjecture of Gaunt et al.1 Moreover, the ratio of the radii of gyration scaling amplitudes seems to be universal.
