Abstract
An isopoly-molybdic acid coordination polymer and a method of manufacturing the same are provided. It relates to the field of catalysts for polylactic acid. A chemical formula of the isopoly-molybdic acid coordination polymer is [MoO(μ-OH)(Htrz)]. Htrz is a 1,2,4-triazole ligand, and (MoO)is a binuclear isopoly-molybdic radical cation. (μ-OH) is the bridging hydroxyl group. Sodium molybdate dihydrate and zinc nitrate hexahydrate undergo hydrothermal reaction in a closed condition to obtain an isopoly-molybdic acid coordination polymer that has a secondary layered structure. The synthesis of the isopoly-molybdic acid coordination polymer is simple with high yield and reproducibility. The isopoly-molybdic acid coordination polymer shows high catalytic activity towards the bulk ring-opening polymerization of lactide. The resulting polylactic acid has a weight average molecular weight exceeding 110,000. The polylactic acid has great potential in the fields of medical, degradable and packaging materials.
