3. Introduction Reversible Addition Fragmentation Chain-Transfer (RAFT) Polymerisation b.RAFT polymerization  Polymerize more versatile monomers in more flexible reaction conditions for a wide range of polymeric architectures  Get rid of the metal catalyst which might complex with some functional groups on proteins and damage the protein bioactivity. a. Atom transfer radical polymerization (ATRP)  Synthesize well-defined polymeric architectures with predictable MW and PDI  Supply a good technique to prepare well-defined protein-polymer conjugate
