Abstract
The present invention is directed to a novel polymerization process for making novel absorbable, linear polylactone polymers prepared using novel polymerization initiators to achieve rates of mechanical property loss or of absorption of articles made from the polymers that are at least about 1.2 times faster than the rates of mechanical property loss of polymers made by similar processes utilizing conventional initiators. The novel polymerization initiators include monols or diols possessing at least one primary alcohol group and two or more carboxylic acid groups. The invention also is directed to absorbable polylactone polymers prepared by processes of the present invention and to medical devices made from such polymers.
