Described herein are biodegradable drug delivery conjugates for effectively delivering bioactive agents to a subject. The drug delivery conjugates comprise a water-soluble high molecular weight linear biodegradable polymer backbone comprising a plurality of linear water-soluble polymeric segments connected to one another by a first (main-chain) cleavable linker, wherein a bioactive agent is covalently bonded to at least one water-soluble polymeric segment, at least one cleavable linker, or a combination thereof. The conjugates possess numerous advantages over prior art delivery conjugates. Also described herein are methods for making and using the conjugates.

Biodegradable Multiblock Poly[<i>N</i>-(2-hydroxypropyl)methacrylamide] via Reversible Addition−Fragmentation Chain Transfer Polymerization and Click Chemistry
was designed, synthesized, and used for direct synthesis of clickable telechelic polymers. Good control of reversible addition−fragmentation chain transfer (RAFT) polymerization of N-(2-hydroxypropyl)methacrylamide (HPMA) was achieved by using the new CTA, as indicated by a linear increase of number-average molecular weight (Mn) with conversion and lowpolydispersity (PDI) (<1.1). In particular, enzymatically
