  1. Polymerization conditions: [AMVN]/[AIBN] = 1.4/1.0 in the molar ratio to the DPDT and iBEA/anisole = 1/1 in weight at 60 °C. The homopolymerization of iBEA or the copolymerization of iBEA and IBoA was carried out during the first-step polymerization, and then 2EHA and HEA were added to synthesize the block copolymers during the second-step polymerization
  2. a Molar ratio to DPDT
  3. b The conversions for iBEA and IBoA indicate the total values of the first- and second-step polymerizations
