GPC curves of macro-RAFT agent (poly(HQHEMA-co-MMA) and poly(HQHEMA-co-St)) and polymers after chain-extension. Chain-extended experiment conditions: [St]₀ : [poly(HQHEMA-co-MMA)]₀: [AIBN]₀= 500 : 5 : 1, 𝑡=24 hour, 𝑇=70^∘C, conversion(%) = 68.6%; [MA]₀ : [poly(HQHEMA-co-St)]₀ : [AIBN]₀= 500 : 5 : 1, 𝑡=3 hour, 𝑇=80^∘C, conversion(%) = 75.3%. Poly(HQHEMA-co-St) (-), poly(HQHEMA-co-MMA) (-), poly(HQHEMA-co-St)-b-PMA (-), poly(HQHEMA-co-MMA)-b-PS (-).
