Abstract
A novel class of polymer-based products for use in physiological environment, e.g. for use as sutures or implanted, medicine-bearing compositions for use in controlled-rate medication, or the like. The advantageous polymers on which these products are based are condensation polymers formed of Krebs cycle acid-type compounds and a physiologically-tolerable polyol type compound such as glycerol or the like.
