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.
XPS研究结果表明,MAO不仅仅只和乙醇作用,MAO还与MgCl_2本身有一定的作用,这是一个极为重要的发现; 3、通过ICP和EDX表征,发现载体的脱醇温度直接影响着元素在固体催化剂中的含量及分布; 4、脱醇温度极大地影响着负载苯氧基亚胺类催化剂的活性和聚合物的性能,特别是原始载体经160℃活化4小时制备得到的固体催化剂MSPC-5的活性明显高于其他脱醇温度条件下制得的固体催化,并且催化剂寿命长,表现出稳定的动力学行为,最终获得了高堆密度(大于0.35g/ml)的球形聚乙烯颗粒; 5、本文选择MSPC-5为研究对象,考察了聚合反应参数对催化剂的活性及其聚合物的影响,研究发现:不同的烷基铝对催化剂具有非常重要的影响,特别足TIBA对MSPC-5的助催化活性最高,烷基铝的加入量有一个较佳值,聚合温度为80度时活性最高,H_2的加入使催化剂的活性明显降低且聚合物的分子量也减小;、新型氯化镁载体负载单活性中心催化剂催化乙烯聚合本文创造性采用固体MAO与无水氯化镁直接进行共研磨,制备出了一种的新型的氯化镁载体,并将该载体用于多种单活性中心催化剂的负载化研究,研究表明: 1、通过BET、XRD的表征,再次证实了MAO与MgCl_2之间具有直接作用,与XPS的研究结果相一致; 2、当研磨时间高于12小时时,延长研磨时间对载体的结构没有显著的影响; 3、将配合物3负载于共研磨时间不同的一系列载体上,乙烯聚合结果表明,尽管共研磨时间对负载催化剂的活性具有明显的影响,但是它对聚合物的性能以及催化剂的影响不明显。

Kubusunan granite is chracterized by low87Sr/86Sr initial values and high ε values, indicating its origin partly from mantle rocks.

Results: A 24-year-old woman suffered from acute painful sensation of both eyes after putting on contact lenses soaked in hydrogen peroxide care solution. Bilateral punctate corneal epithelial erosions were diagnosed. To relieve pain, she, by herself, applied topical 0.5% proparacaine eye drops to both eyes with increasing frequency to almost hourly. However, the pain was aggravated. On examination 2 days later, a large central disciform epithelial defect and diffuse edema of the residual epithelium were noted in both corneas. With the treatment using non-preserved artificial tears, the epithelial defects started to heal the next day and ring-shaped stromal cellular infiltrates were observed at the border of previous epithelial defects.
