A range of well-defined guanidinium-rich linear polymers with demonstrable efficiency for cellular internalization were developed. A protected guanidinium-functional acrylamide monomer (di-Boc-guanidinium ethyl acrylamide, GEAdiBoc) was synthesized and then polymerized via RAFT polymerization to yield well-defined homopolymers, which were then deprotected
