Figure S1. Conductivity (a) and equivalent conductivity (b) data for MUTAB and micelle
polymerized polyMUTAB (KCl is plotted as a solid line for comparison). The break in the MUTAB
conductivity indicates the position of the CMC (~25 mM), while the lower conductivity and lack of a
clear break in the curve for the polyMUTAB sample indicates that there is no detectible CMC.
The conductivity versus concentration, κ vs c, for MUTAB and micelle polymerized MUTAB are
shown in Figure S1a. The equivalent conductivity versus the square root of concentration, Λ = κ/c vs
c1/2, is shown in Figure S1b. The conductivity at low concentrations can be fit as Λ = Λο - Ac1/2, where
for simple electrolytes Λο is the limiting equivalent conductivity which can be expressed as the
addition of the limiting equivalent conductivities of the individual ions (i.e. Λο = λoC+ + λoBr-) and A is
a constant. For polyelectrolytes, the same equation is usually valid but the limiting conductivities
depend on multiple factors such as the counterion binding and the conformation of the polymer in
solution.
