Özet

The terminal alkyne homocoupling reaction (oxidative alkyne coupling) is presented here as a new route for the preparation of A₂B₂ type 4-miktoarm star copolymer. The block copolymer with terminal alkyne at the junction point prepared by NMP-ATRP and ROP-NMP sequential routes is coupled via diyne formation to give (PS)₂-(PMMA)₂ and (PCL) ₂-(PS)₂ 4-miktoarm star polymers, respectively, by using a combination of (PPh₃)₂PdCl₂/PPh ₃/CuI in a solvent mixture of Et₃N/CH₃CN at room temperature for 72 h. The molecular weight, intrinsic viscosity ([η]), radius of gyration (R_g), and hydrodynamic radius (R_h) of A₂B₂ 4-miktoarm star copolymers were calculated using triple-detection GPC as results of three detectors response.
