✦ Synopsis

A novel synthetic route to heterobifunctional poly(ethylene glycol) containing both amino and carboxylate terminal groups was established via anionic polymerization of ethylene oxide using (cyanomethyl)potassium as the initiator, followed by the successive conversion of the end-hydroxyl group to a primary amino group, and hydrolysis of the cyano group to a carboxylate group.

## Abstract A poly(ethylene oxide)‐__block__‐poly(dimethylamino ethyl methacrylate) block copolymer (PEO‐__b__‐PDMAEMA) bearing an amino moiety at the PEO chain end was synthesized by a one‐pot sequential oxyanionic polymerization of ethylene oxide (EO) and dimethylamino ethyl methacrylate (DMAEMA)
