SYNTHESIS OF WELL-DEFINED STAR AND BLOCK COPOLYMERS BY LIVING/CONTROLLED POLYMERIZATION

摘要

@@Synthesis and properties of functional polymeric materials have attracted much attention in current polymer science.1-4 Some complex macromolecular architectures such as block, star, graft and hyperbranched polymers have been achieved by living/controlled polymerization. Among them, star polymers possess branched structures and usually exhibit unique physico-chemical properties different from those of their linear analogs, and synthesis of miktoarm star polymers with different arm segments is very interesting due to their more complex selfassembly properties and microphase-separated suprastructures.
