Abstract
A downhole tool or a component thereof may comprise a plasticized polymer composition that comprises a polymer and a water-soluble plasticizer, wherein the plasticized polymer composition has a first deflection test value. The tool may be exposed to an aqueous-based medium where the water-soluble plasticizer may leach out of the tool such that the plasticized polymer composition has a second deflection test value after exposure to the aqueous-based medium that is less than about 10% of the first deflection test value.
