Synthesis and Self-Assembly of Pore-Forming Three-Arm Amphiphilic Block Copolymers.

The synthesis of an amphiphilic three-arm block copolymer (AB)-BCP, which consists of poly(methyl methacrylate) (PMMA) and poly(butyl methacrylate) (PBMA) in the hydrophobic inner block, is reported. The hydrophilic block segment is based on poly(2-hydroxyethyl methacrylate) (PHEMA) originating from 2-(trimethylsiloxyl)ethyl methacrylate (HEMA-TMS). The preparation is carried out in two steps using a core-first approach.
