Two samples of ABCD 4-miktoarm star quarterpolymer with A = polystyrene (PS), B = poly(ε-caprolactone) (PCL), C. = poly(methyl methacrylate) (PMMA) or poly(tert-butyl acrylate) (PtBA), and D = poly(ethylene glycol) (PEG) were prepared using click reaction strategy (Cu(I)-catalyzed Huisgen [3 + 2] reaction). Thus, first, predefined block copolymers of different polymerization routes, PS-b-PCL with azide and PMMA-b-PEG and PtBA-b-PEG copolymers with alkyne functionality, were synthesized and then these blocks were combined together in the presence of Cu(I)/ N,N,N′,N″,N″- pentamethyldiethylenetriamine as a catalyst in DMF at room temperature to give the target 4-miktoarm star quarterpolymers. The obtained miktoarm star quarter polymers were characterized by GPC, NMR, and DSC measurements.
