Hexadecane (HD, Sigma-Aldrich) and sodium dodecyl sulfate (SDS, Sigma-Aldrich) was used as received. MilliQ water was used for miniemulsion experiments. Characterizations Conversion was measured using gravimetry by drying samples in a vacuum oven at 40 °C. The molecular weight and molecular weight distribution was measured by gel permeation chromatography (GPC). Tetrahydrofuran (HPLC grade, 0.05% w/v 2,6-dibutyl-4-methylphenol (BHT)) was used as the eluent at 40 °C and at a flow rate of 1 mL/min. The GPC system was comprised of a Shimadzu SIL-10AD auto-injector, a Polymer Laboratories 5.0 μm bead-size guard column (50x7.5 mm 2 ), 4 linear PL (Styragel) columns (10 5 , 10 4 , 10 3 and 500 Å) and an RID-10A differential refractive index (RI) detector and UV-Vis detector.
