| المستخلص: |
Synthesis of nano-composites material namely polypropylene-silica nano-composites were investigated. Interested results were obtained for insertion silica nano-particle in polypropylene using in-situ polymerization with methyl-aluminoxane (MAO) activated metallocene catalyst in the presence of the metallocene catalyst. Different amounts of the MAO modified silica were added to the activated catalyst which, in turn leads to nano-composites with different silica loads. C2 symmetric ansa metallocene, ethylene-bis (indenyl) zirconium dichloride (EI), was used in this study. The effect of addition MAO modified silica and polymerization temperature on the catalyst activity in the in-situ polymerization was investigated. The morphology, crystallization behaviors and crystallization degree of the synthesized nano-composites were also investigated. Promising results were obtained and showed that nano-composites with improved properties and retention of the high activity of the metallocene catalyst could be prepared via in-situ polymerization. |
