  • Process for preparing reabsorbable polyesters by mass polymerization
    Patent number: 6706854
    Abstract: The invention relates to a process for preparing reabsorbable polyesters by bulk polymerisation, wherein the reaction components are melted and homogenised in a stirred reactor, the reaction mixture is then transferred into a number of smaller-volume containers, the reaction mixture is polymerised in these containers and the polyester obtained is isolated by removing it from the containers, and the use of the reabsorbable polyesters thus produced for preparing reabsorbable implants.
    Type: Grant
    Filed: January 9, 2003
    Date of Patent: March 16, 2004
    Assignee: Boehringer Ingelheim Pharma GmbH & Co. KG
