The particle volume fraction as a function of temperature, (pp(T) was determined from swelling experiments. The change in linear size of the microgels as it swells was converted into a particle volume expansion ratio ap(T, and was then modeled using an empirical sigmoid equation with the results presented in Figure 4a. The results were subsequently used to calculate (pp(T) as shown in Figure 4b.
