Abstract

Fremgangsmåte for fremstilling av polyglykolsyre av sutur-kvalitet ved polymerisasjon av et glykolid som er renset ved oppløsning i et organisk løsningsmiddel, tilsetning av aluminiumoksyd til den resulterende løsning under dannelse av en oppslemming, hvori aluminiumoksydet er i intim kontakt med det oppløste glykolid, omrøring av oppslemmingen i 1 til 60 minutter, og filtrering av oppslemmingen som fjerner aluminiumoksydet.Process for preparing suture grade polyglycolic acid by polymerizing a glycolide which has been purified by dissolving in an organic solvent, adding alumina to the resulting solution to form a slurry in which the alumina is in intimate contact with the dissolved glycolide, stirring the slurry for 1 to 60 minutes, and filtering the slurry that removes the alumina.
