Synthesis and Assembly of Poly(Ethylene Glycol)-b-Poly(N-Dodecyl Glycine)Based Diblock Copolymers
A diblock copolymer poly(ethylene glycol)-b-poly(N-dodecylglycine)(PEG-b-PNDG)by ring-opening polymerization(ROP)was prepared.The crystallization behavior of the block polymer was characterized by DSC.The polymer can be assembled in mixed organ-ic solvents with different proportions of dioxane and chloroform to form spherical micelles and spherical aggregates with diameters of about 40 nm and 220 nm,respectively.The syn-thesized polymers have good biocompatibility and potential applications in the fields of drug carriers and the like.
