Abstract

Disclosed herein are polyesteramide random copolymers having high glass transition temperatures, methods of forming such polymers, devices, formulations, and medical devices containing such polymers, and methods of treating mammals suffering from various conditions using such polymers in combination with a bioactive agent. In an embodiment, the random copolymers may have a Tg above body temperature, about 37° C., and may achieve a longer release duration, different release kinetics, improved barrier properties, or other benefits over polymers with Tg below 37° C.
