Patent number: 8309623Abstract: The disclosed is a biodegradable copolymer, an amphiphilic diblock copolymer, composed of a hydrophilic segment and a hydrophobic segment. The hydrophilic segment is an endcapped PEG or derivatives thereof. The hydrophilic segment is a random polymer polymerized of lactone or cyclic C3-C6 molecule and lactic acid/glycolic acid. There is no coupling agent between the hydrophilic and hydrophobic segments, and the biodegradable copolymer is formed by one-pot ring-opening polymerization. The biodegradable copolymer can be dissolved in water to form a thermosensitive material having a phase transfer temperature of 25 to 50° C., thereby being applied to biological activity factor delivery, tissue engineering, cell culture and biological glue.Type: GrantFiled: November 23, 2010Date of Patent: November 13, 2012Assignee: Industrial Technology Research InstituteInventors: Ya-Jen Yu, Chin-Fu Chen, Tsai-Yu Lin, Shao-Jen Yeh, Shian-Yih Wang, Po-Liang Lai
