Supramolecular chemistry has emerged as a route to prepare complex polymer architectures using complimentary polymeric building blocks. In addition, unique properties, such as self-healing, have been obtained due to the reversibility of the bonding. This talk will focus on linear block copolymers formed through electrostatic interactions of oppositely charged (semi)telechelic polymers. Previous investigations have shown interesting behavior including microphase separation analogous to covalently bonded block copolymers and macrophase separation due to charge dissociation at elevated temperature. The synthesis of new (semi)telechelic ionomers using controlled free radical polymerization techniques (ATRP and RAFT) and post-polymerization modification will be presented. These synthesis routes expand the range of possible building blocks and enable the synthesis of polymer libraries to carry out combinatorial synthesis of new block copolymers.
