11. Polymeric micelles are drug carriers formed by the aggregation of some amphiphilic molecule with an amphiphilic block copolymer . 12. Lodge's recent work has focused on the self-assembly of block copolymers in ionic liquids. 13. For example, Nylon-rubber bands are polymerized with functionalized rubber to produce graft or block copolymers . 14. The addition of an amphiphilic block copolymer effectively lowers this critical micelle concentration by shifting the monomer exchange equilibrium. 15. Preparation of block copolymers by iodine-transfer polymerization was also described by Tatemoto and coworkers in the 1970s. 16. Styrene-butadiene block copolymer ( SBC ) is a thermoplastic resin that is transparent and impact-resistant. 17. Micelles of the gradient copolymer can form when the gradient copolymer concentration is too high in a block copolymer solution. 18. Eventually, Tirrell's work on block copolymers led him to starting research in the field of peptide amphiphiles. 19. The advantage of this method is that polymers and block copolymers of well-defined molecular weight can be easily prepared. 20. It has been used as the hydrophobic block of amphiphilic synthetic block copolymers used to form the vesicle membrane of polymersomes.
