methods that include a method comprising : providing a degradable polymer and one solvent , wherein the solvent comprises an aqueous fluid selected from the group consisting of fresh water , salt water , brine , seawater , and combinations thereof ; combining the degradable polymer and the solvent to form a degradable polymer composition ; allowing the degradable polymer to at least partially plasticize ; and applying sufficient shear to the degradable polymer composition so that degradable particulates begin to form . additional methods are provided .
