We plot the simulation behavior of [η] as a function of the overall molecular weight M and backbone molecular weight M bb for a number of different side chain lengths M sc in Figure , M bb (Da) as well as for a linear molecule. Notably, we observe the general trends associated with the regimes plotted in the experimental comparison in Figure ; the initial weak dependence on M associated with a star-like geometry shows an increase in [η] commensurate with the increase in the branch length, because the star-like structure is thus larger. The upswing in the intrinsic viscosity occurs also at a larger value of M for longer M sc , because the backbone needs to be sufficiently long to register an extension of the bottlebrush structure beyond the length of the side chains. The terminal scaling exponent is plotted as ν v versus the side-chain M sc , showing that there is a small but non-negligible increase due to the side-chain induced stiffening of the bottlebrush structure. This is consistent with the experimental scaling values shown in Figure and also with prior experimental work on polystyrene bottlebrushes. 112
