Abstract
A lactide-functionalized polymer is synthesized by polymerizing a monomer capable of undergoing radical polymerization (e.g., styrenic, vinylic, acrylic, etc.) using a brominated lactide initiator via atom transfer radical polymerization (ATRP). In some embodiments of the present invention, the brominated lactide initiator is 3-bromo-3,6-dimethyl-1,4-dioxane-2,5-dione prepared by reacting lactide with N-bromosuccinimide in the presence of benzoyl peroxide.
