Abstract
In conclusion, LA polymerization in the presence of CF3SO3H yielded various block copolymers composed of PEG and PLLA, even at room temperature, via an activated monomer mechanism. The PLLAs obtained had molecular weights close to the theoretical values calculated from the LA/PEG molar ratios, and no side reactions were observed. We believe that this ROP system may extend the use of PEG and PLLA block copolymers in practical biomedical applications.
