Long-chain branched poly-3-hydroxyl-butyric acid thread for implantate has long-chain branches numbering at least 0.05 per 1000 monomers

摘要

The long-chain branched poly-3-hydroxyl-butyric acid thread for implantate has long-chain branches numbering at least 0.05 per 1000 monomers, and short chains comprising at least 2%, preferably at least 3%, of the average molecular weight. The threads crystallize out almost completely in the alpha and beta modifications.
