Given are various data collections acquired for the PEMA75-b-PDMAEA50 polymer at a 10 mg/mL concentration in THF. In the given measurement series, the total overall flow rate, and the mixing ratio of the water and THF/polymer stream is systematically varied, spanning a measurement space of 1 to 8 mL/min total flow rate and mixing ratios from 90/10 to 50/50 (lower water contents don't lead generally to stable particle formations and hence were not considered).
