Triblock copolymers can be prepared from diblock copolymers by a third monomer addition. They can also be prepared using a bis-funetional NMP or ATRP initiator or a bis-RAFT agent (for examples, see Table 9.13). Symmetrical trithiocarbonates (Table 9.15) should also be considered as bis-RAFT agents in... 

VPr), and simifar monomers. Other RAFT agents may be required for soiubifity or compatibility with particular polymerization media or to provide specific end-group functionality. Hie rrse of bis- and multi-RAFT agents (see Section 3.07.3.4.4) permits the synthesis of polymers with complex architectmes. Symmetrical trithiocarbonates can be considered as a member of the class of bis-RAFT agents.
