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

Abstract

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 $⟨s_N^2⟩\propto N^{2\nu }$, 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.
