Abstract
Disclosed is a process for producing lactide-based copolymers and copolymers produced by the process. The copolymers are formed by the copolymerization of a lactide monomer with a secondary material. In one embodiment, the secondary material can be derived from renewable resources, providing a product copolymer completely derived from renewable resources. The disclosed materials may display improved hydrolytic and thermal characteristics as compared to previously known lactide-based materials. Exemplary secondary materials that can be copolymerized with lactide can include polyhydroxy alkanoates, long chain primary alcohols, and depsipeptides.
