摘要：

PLLA-POE-PLLA block copolymers were prepared using PLLA and POE with different compositions. Copolymers were obtained in high yield and the polydispersity of the copolymers was very narrow. A dispersed solution of 0.1 g/mL of PLLA-POE-PLLA copolymer was mixed with a dispersed solution of 0.1 g/mL of PDLA-POE-PDLA copolymer. Gel formation was observed from the mixed product obtained at the human body temperature of 37 degreesC. The mixed product comprising PDLA-POE-PDLA and PLLA-POE-PLLA was found to have higher cloud points than that of PLLA -POE -PLLA copolymer. The cloud points decreased with increasing the concentration of the mixed copolymer dispersed solution.
