The polymerization is performed at 80°C, initiated with 0.5 mol% of azobisisobutyronitrile (AIBN), in solution (anisole; 50 v%) to minimize the gel-effect. The introduction of 5 mol% of DOT in the batch recipe does not lead to any change in the overall conversion compared to the DOT-free MMA polymerization, and produces a poly(methyl methacrylate) (PMMA) with roughly similar average molar masses (see Figure and S2 in Supporting Information). A double detection SEC, using DRI/UV(254 nm) detectors, was performed to determine if any DOT moieties were inserted into the backbone for a MMA/DOT copolymerization (Figure ).
