Abstract
In one aspect, the invention relates to processes for producing substantially free-flowing shapes of macrocyclic oligoester, wherein the freshly-shaped macrocyclic oligoester is maintained at elevated temperature for a sufficient time. In certain embodiments, the shapes are heated in water, thereby avoiding agglomeration during the heating process itself. In another aspect, the invention relates to processes for removing solvent from a solution of macrocyclic oligoester using elevated temperature, reduced pressure, or both, thereby obviating the need for an anti-solvent to precipitate the macrocyclic oligoester from the solution. Other aspects of the invention related to shaping of macrocyclic oligoesters are presented as well.
