SYNTHESIS AND SELF-ASSEMBLY OF A NOVEL AMPHIPHILIC COPOLYMER CONSISTING OF A POLYPHOSPHORAMIDATE HEADGROUP AND MANY POLY(L-LACTIDE) TAILS

摘要

@@Due to the unique physical and chemical properties, hyperbranched polymers have been arising enormous interest of many scholars and exhibited potential applications in such areas as catalysis, photoelectrics, polymer processing additives, biomedicines and pharmaceutics, etc..1 Amphiphilic linear polymers can self-assembly into micelles that have long been a focus study of polymer science. These macromolecules could aggregate into various morphologies such as micelles, vesicles, tubes and lamellae with potential applications in medical industry, especially for nano drug delivery system and gene carriers.2-4 In contrast, amphiphilic hyperbranched polymers have more complex structures and the self-assembling behaviors of amphiphilic hperbranched polymers are variable and diverse.
