Abstract: An isopoly-molybdic acid coordination polymer catalyst for manufacturing polycaprolactone and method of manufacturing the same are provided. It relates to a field of catalysts from polycaprolactone. The chemical formula of the isopoly-molybdic acid coordination polymer catalyst is [Cu2(trz)2(γ-Mo8O26)0.5(H2O)2]. In the chemical formula, trz is 1,2,4-triazole negative monovalent anion, and [γ-Mo8O26] is a γ type octamolybdate anion. This synthesis method offers higher yield with strong reproducibility. The resulting crystal products have higher purity. The isopoly-molybdic acid coordination polymer catalyst shows high catalytic activity towards the bulk ring-opening polymerization of caprolactone. The resulting polycaprolactone has a weight average molecular weight exceeding 50,000 and a narrow molecular distribution. The polycaprolactone has great potential in the application of low- to medium-temperature thermoplastic medical materials.
