采用阴离子配位聚合法,以高聚物负载型双金属氰化物复合体（DMC）作为催化剂,合成了二氧化碳、环氧丙烷二元共聚物：聚碳酸亚丙酯（PPC）。并以聚乙烯醇PVA-1788为水相稳定剂,采用乳化溶剂挥发法制备毒死蜱微胶囊。采用土壤悬浊拟环境培养实验法评价了PPC的降解性能。通过光学显微镜（OM）、扫描电子显微镜（SEM）、广角X射线衍射（W-XRD）、高效液相色谱（HPLC）等表征农药微胶囊的性能。结果表明,PPC具有生物可降解性,所得的PPC-毒死蜱微胶囊球形规整,表面光滑。95%的微胶囊粒径在3~10μm范围内,载药量和包封率分别达到16.75%和89.34%。微胶囊释药性能研究表明,PPC-毒死蜱微胶囊具有明显的缓释...

Poly(propylene carbonate)(PPC) was synthesized by anionic coordination polymerization of carbon dioxide and propylene epoxide, double metal cyanide complexes (DMC) as catalyst. The chlorpyrifos microspheres were prepared by emulsion solvent volatilization method with PVA-1788 as stabilizer. The degradation performance of PPC was evaluated by simulated soil suspension environment experiment. The properties of the pesticide microcapsule were characterized by scanning electron microscope, optical microscope, wide-angle X-ray diffraction spectra an...
