Living cationic polymerization and the combination of living polymerization techniques have been proven to be powerful tools in the design and synthesis of PIB based block copolymers. These methods provide well-defined and compositionally homogeneous linear and star-branched materials. These block copolymers combining immiscible plastic-rubbery, crystalline-rubbery, and hydrophobic-hydrophilic block segments are valuable model materials for structure-property investigation, and potentially useful materials as elastomers, impact modifiers, compatibilizers, adhesives, etc.. Growing industrial interest especially in thermoplastic elastomers and materials for biomedical applications encourage further research in this area. |
