| titleOfInvention | Zinc coordination polymer catalyst for preparing polyglycolic acid and preparation method thereof |
| abstract | The present invention relates to zinc coordination polymer catalyst for preparing polyglycolic acid and preparation method thereof, it is related to polyglycolic acid catalyst field.Its chemical formula is [Zn (BDC) L], and BDC is p-phthalic bridge anion in formula, the tetrachloro N, N' bis- of L 2,3,5,6（4 pyridines）Diamide ligand.The present invention is using zinc nitrate hexahydrate and organic ligand terephthalic acid (TPA) and 2,3,5,6 tetrachloro N, N' bis-（4 pyridines）Diamides obtains a kind of zinc coordination polymer of the diamond three-dimensional net structure containing quadruple IPN under sealing condition in N, N dimethylformamides via thermal response.The synthetic method yield that the present invention shows is high, favorable reproducibility；The crystal purity of gained is high.The catalytic activity that the zinc coordination polymer has had to catalysis glycolide ring-opening polymerisation, the polyglycolic acid weight average molecular weight of preparation can be applied in medical macromolecular materials field more than 60,000. |
