Abstract

We investigate the excluded volume effects in good solvents for the isolated comb polymers having ν₀=1/4. In particular, we investigate the change of the size exponent, ν, defined by ⟨ s_N²⟩∝ N^2ν, for the various fully-expanded configurations. The results show that, given the fully stretched backbone and side chains, the exponent takes the value, ν=1/2, irrespective of the configurational isomerization of side chains; only the pre-exponential factor changes.
