  1. aCalculated from the monomer conversions
  2. bThe number-averaged molecular weight (Mn) and dispersity (Đ) were determined using conventional GPC against PSt standards in CHCl3
  3. cTg was defined as the temperature corresponding to the maximum tan δ value in the DMA measurement
  4. dTd5 and Td50 were defined as the temperatures at which the weight loss reached 5 and 50%, respectively, of the total weight in a nitrogen atmosphere
  5. eBimodal in GPC as for entries 10–13
