Dealcoholization temperature markedly influences the surface area and porosity of the resultant MAO-supports. When the support was pretreated at lower or higher temperature, the corresponding MAO-support shows very low surface area; 2.XRD and IR analyses indicate that MAO has reacted with the residual ethanol in the supports, which is an important manner to get MAO fixed on the carrier. Morever, XPS analyse indicates that MAO can also be coordinated with MgCl_2, which is another way to get MAO fixed on the support; 3.ICP and EDX analyses indicate that dealcoholization temperature not only determined the element content on the solid catalyst, but also influences the element distribution on the carrier; 4.The activities of the supported phenoxy-imine catalysts and the properties of resultant polymers are strongly dependent on the dealcoholization temperature. The support (MSP-5) obtained by treating MgCl_2·2.56C_2H_5OH at 160℃for 4 h, then modified by MAO is very effective for immobilizing complex 3, the resultant solid catalyst (MSPC-5) shows very high activity in ethylene polymerization, and its kinetics of polymerization is stable during the reaction process. Finally, PEs with spherical morphology and high bulk density (over 0.35g/ml) were obtained, without reactor fouling; 5.In this work, polymerization conditions such as alkylaluminums, Al/Zr ratio, temperature and H_2 had a pronounced effect on the activity of MSPC-5 and properties of PE;(3). New MgCl_2-Supported Single-Site Catalysts for Ethylene Polymerization In this work, a kind of new MgCl_2 support was obtained by anhydrous MgCl_2 co-milled with solid MAO, and it is a creative contribution. Then some single-site catalysts were supported on the new MgCl_2 support, and the resulted solid catalysts were tested in ethylene polymerization, the results indicated that: 1.XRD and IR analyses indicate that MAO does be coordinated with MgCl_2, which is in good agreement with the results obtained by XPS; 2.co-mlling time had no obvious effect on the texture of support after 12 hours; 3.In this work, MgCl_2 was co-milled with solid MAO for different hours, and then complex 3 was supported on these co-milled supports. It was found that co-milling time markedly influences the activity of solid catalysts, but it had negligible effect on the kinetic profile and the properties of resultant PE.

The chemistry behavior research of wollastonite indicated that the silicon-potassium fertilizer has a chemical active in organic acid.The factors affecting manurial effect of silicon-potassium fertilizer are not only soil pH and desilicification,but also content and type of organ in the soil.Wollastonite chemistry behavior indicates that silicic acid can be dissolved out from silicon-potassium fertilizer in chlorhydric acid solution if pH of solution is not smaller than 2. The drop of apparent density,increase of DBP sorptive rate and specific surface for leavings indicate that hydrated silicon oxide is polyporous,and those mineralogic feature presignify that silicon-potassium fertilizer has a role of conservation of both Moisture and Fertility and improving soil structure.After active ingredient releasing,silicon-potassium fertilizer leaves half the substance (non-active ingredient)in soil.

After a study on Chinese financial practice, we find that though Chinese banking system has high cost and low efficiency, one side, Chinese security market has very low efficiency to overcome asymmetric information and has many unsolved problems in short term that brings very high additional cost, so security market is not a good system to substitute the Chinese banking system and must develop after these problems are solved, on the other hand, the cost of Chinese banking system is mainly exogenously produced, the experiences of western commercial banking practice and the joint-stock reform in some Chinese banks have proved that the efficiency of Chinese banking system can be improved. So one of our conclusions is that China should emphases on the reform and development of the banking system.

The aim of this study was to develop a novel amphiphilic functional block poly(ε-caprolactone) bearing ketone groups MPEG-b-P(OPD-co-CL. 2-oxepane-1, 5-dione was copolymerized with ε-caprolatone in which methoxy poly (MPEG, Mn=5 000) and stannous octoate were used as initiator and catalyst, respectively. The syntheses were conducted by bulk and solution polymerization. 1H NMR results showed that peak position and splitting of the polymers synthesized through solution polymerization were consistent with theoretical data, demonstrating the products were designed block copolymers. While in the bulk polymerization, polymer peak position was changed due to their high reaction temperature, suggesting their structural variation.
