Advances in Biomedical Polymers

This book is derived from a Symposium held at the 190th National American Chemical Society Meeting, which was held in the Fall of 1985, in Chicago, and was sponsored by the Division of Polymeric Materials: Science & Engineering. This Symposium was, in turn, a follow-up on an earlier one held in Houston, TX, in the Spring of 1980, which was pub lished as the book ·Biomedical and Dental Applications of Polymers· [Plenum Press, New York, 1981]. In that earlier book, our opening Preface passage quoted King David, ·1 will praise Thee; for I am fearfully and made . •• • (Psalm 139:14). As we noted five years ago, sickness wonderfully of many types does occur in our wonderfully made bodies, but much human suffering can be aided by biomedical polymers. That earlier book con sidered much of the fantastic progress that had been made in biomedical polymers during the previous quarter century and brought many of these topics up to date. That Symposium, and book, noted that much help was available for the varied afflictions and problems that sometimes beset, and upset, our God-given bodies, and the promise of new and important advances was held out as a shining ray of hope amidst the gloom of sickness and affliction. The present volume is an update on the advances that have occurred since the 1981 book and sets the stage for even greater advances in the future.
