Preparation of the P(MAG-b-methacrylate) nucleic acid delivery vehicles via RAFT polymerization that contain blocks of a methacrylate monomer with pendant primary amine (PAEMT), secondary amine (PMAEMT), tertiary amine (PDMAEMT), and quaternary ammonium groups (PTMAEMT). At the pH of biological media (7.2-7.4), the some of the amines along the backbone exhibit a positive charge, which facilitates binding and compaction of polynucleotides.
