摘要： A biodegradable cationic polymer is disclosed, comprising first repeat units derived from a first cyclic carbonyl monomer by ring-opening polymerization, wherein more than 0% of the first repeat units comprise a side chain moiety comprising a quaternary amine group; a subunit derived from a monomeric diol initiator for the ring-opening polymerization; and an optional endcap group. The biodegradable cationic polymers have low cytotoxicity and form complexes with biologically active materials useful in gene therapeutics and drug delivery.
