ABSTRACT:
In the method of the invention, plasticizer is extracted from a polymeric film electrode, electrolyte or laminated film structure thereof, by contacting the film, with an extraction solvent mixture comprising a polar co-solvent, and carbon dioxide which is in a solvent fluidic state, at a temperature greater than or equal to 31.degree. C. and less than 35.degree. C. The pressure of extraction is sufficient to maintain the fluidic state at the temperature range stated. The co-solvent is present in an amount up to about 10% by weight of the extraction solvent mixture. The co-solvent is characterized by having a liquid state at the temperature and pressure of extraction.
