Abstract: Unsaturated polyester resins and processes for making the same are disclosed herein. In particular, the process for making the resin provides resins with improved properties. The unsaturated polyester resins have substantially reduced free fumaric acid as compared to that made from conventional processes. The toner resins are used to prepare toner compositions that have improved performance.
