finding 𝑅 𝑔 to be 7 nm and 12 nm corresponding to the number-averaged and weight-averaged molecular weights, respectively. This result suggests that if PII-2T exists as dispersed polymer chains in dilute solution then the SAXS profile should exhibit a Guinier knee corresponding to the overall chain size at 𝑞 ~ 0.01 Å -1 and a constant flat intensity below this value.
