For the TR-SANS measurements, a rectangular cell with a 0.1 cm thickness was used along with a neutron wavelength of λ = 6 Å and a wavelength resolution of ∆λ/λ = 0.1. A detector distance of 17.6 m was used, with continuous counting of the scattered neutrons for 15 s after mixing, which was consequentially binned into 50 ms intervals, before radial averaging and normalization. Several measurements were also done at longer time scales, the last at 5 minutes to confirm the final state.
