Preparation and Evaluation of Glycolic and Lactic Acid-Based Polymers for Implant Devices Used in Management of Maxillofacial Trauma

Abstract

Glycolide and L-lactide were synthesized and purified to monomer grade materials. Polymers and copolymers were prepared from the monomers, and the polymers were evaluated by flexural property measurements, DTA, and GPC. Rods were fabricated with 5mm X 10 in. dimensions by injection molding. Pellets, 2mm X 2mm, were fabricated. Similar pellets were also fabricated, incorporating C-14-labelled glycolic acid and tritium-labelled lactic acid moieties.
