a copolymer comprising a bioabsorbable , segmented molecular architecture has been invented . the copolymer has at least two different ester linkages . the segmented molecular architecture comprises a plurality of fast transesterifying linkages . the fast transesterifying linkages have a segment length distribution of greater than 1 . 3 . the segmented molecular architecture also comprises a plurality of slow transesterifying linkages . the following proviso is a material limitation to this invention : for the fast transesterifying linkages consisting essentially of glycolate linkages and the slow transesterifying linkages selected from the group consisting of trimethylene carbonate and caproate linkages , the segment length distribution of the fast transesterifying linkages is up to 2 . 0 and the number average segment length of the slow transesterifying linkages is greater than 2 . 5 linkages per segment . the copolymer is useful as an article of manufacture , for example a molding resin , surgical element and controlled release device .
