| 英文摘要 | The polymerization of methyl 3-hydroxypropionate as monomer catalyzed by lipase was selected as a model system in this study. The monomer with the purity around 95% could be polymerized to polyhydroxyalkanoates in the catalysis of Novozym 435. Decreasing the reaction pressure would result in the increase of product yield and high molecular weight. By choosing appropriate organic solvents, surfactants and reaction pressure, the molecular weight of polyhydroxy propionate polyester could be controlled from 1800 to 13000 (Mw value). The reusing ability of enzymatic catalyst was comparatively good. The relative activity could be maintained above 95% after 6 repeated batches reaction. |
