This volume is a eoLleetion of manuseripts based on presenta tions at a symposium "Polymerie Separation Media" organized for the Seeond Chemieal Congress of the North Ameriean Continent held in Las Vegas, August 24-29, 1980. The symposium was organized to bring together researehers in the expanding field of separations based on polymerie media. A diverse eross-seetion of re.seareh areas were presented, whieh were linked by the aetive separation agent being a polymerie material. I would like to thank the authors for their endeavours and the audienee for their partieipation, espeeially in light of the late change of venue for this meeting. Finally I am indebted to the Division of Polymer Chemistry Ine. of the Ameriean Chemieal Soeiety for their sponsorship. Anthony R.
