Branched Polymers with Excluded Volume Effects/ Configurations of Comb Polymers in Two- and Three-dimensions

We investigate the excluded volume effects in good solvents for the isolated comb polymers having $\nu_{0}=1/4$. In particular, we investigate the change of the size exponent, $\nu$, defined by $\langle s_{N}^{2}\rangle\propto N^{2\nu}$, for the various fully-expanded configurations. The results show that, given the fully stretched backbone and side chains, the exponent takes the value, $\nu=1/2$, irrespective of the configurational isomerization of side chains; only the pre-exponential factor changes.
