Eight-armed A4B4-type hetero-arm star-shaped PCL-PLA polymers ((PCL)4-POSS-(PLA)4, SPLA3 with POSS core were successfully prepared via combination of the "arm-first" approach utilizing ring-opening polymerization (ROP) and click chemistry techniques. Firstly, alkyne-functional PLA and PCL polymers having arms with 30 repeating units were synthesized via ROP with utilizing propargyl alcohol as initiator and stannous octoate (Sn(Oct)2) as catalyst. Then, the obtained hetero-armed star-shaped polymers were prepared by Cu(I)-catalyze
