Abstract
AB diblock copolymers consisting of PBLG as the hydrophobic part and PNIPAAm as the hydrophilic one were prepared by polymerization of BLG‐NCA with semitelechelic PNIPAAm with amino end group as initiator. The core‐shell type nanoparticles of the block copolymers were obtained by the diafiltration method. The sizes of the nanoparticles were from about 73 to 359 nm and the shapes of them were spherical. The release for indomethacin (IN) from the nanoparticles was faster at 28°C than at 34°C due to the conformational change of PNIPAAm by temperature.
