摘要

A new strategy to synthesize a series of well-defined amphiphilic PEO-b-PS-b-PCL block copolymers is presented. First, bromine-terminated diblock copolymers PEO-b-PS-Br are prepared by ATRP of styrene, and converted into azido-terminated PEO-b-PS-N₃ diblock copolymers. Then propargyl-terminated PCL is prepared by ROP of ε-caprolactone. The PEO-b-PS-b-PCL triblock copolymers with M̄_n from 1.62 × 10⁴ to 1.96 × 10⁴ and a narrow PDI from 1.09 to 1.19 are finally synthesized from these precursors. The structures of these triblock copolymers and their precursors have been characterized by NMR, IR, and GPC analysis.
