Notes:
Amphiphilic diblock copolymer was synthesized in one-step or two-step process by usingof methoxy polyethylene glycol (MePEG), 1,6-hexanediol and maleic anhydride and characterizedby FTIR and GPC. IR spectrum of amphiphilic diblock copolymer confirmed that MePEG hadgrafted on polyester. Solution polycondensation, melt polycondensation, mode of adding monomersand reaction time were studied on effect of molecular weight and its distribution. The GPC resultsshowed that fairly narrow molecular weight distribution was obtained in solution polycondensationby one-step process. In addition, self-assemble behavior of amphiphilic diblock copolymer wasdiscussed in different solvents by nanoprecipitation technique. The micelle size and aggregationwas measured by TEM. It was found that MePEG1900-b-Polyester2162 copolymer self-assembled inacetone solution against water into well core-shell nanoparticles
