Abstract
Disclosed is a process for producing lactide-based copolymers and the copolymers produced by this process. Disclosed copolymers are formed in one embodiment through the copolymerization of a lactide monomer with a fluorinated diol, for example a perfluorinated polyether monomer, oligomer or copolymer. The disclosed materials may display improved mechanical characteristics, hydrolytic characteristics, and thermal characteristics as compared to previously known lactide-based materials.
