| 摘 要： | 以介孔分子筛SBA-15为载体负载二氯二茂锆配合物制备了SBA-15负载二氯二茂锆催化剂,在助催化剂MMAO作用下,该负载催化剂常压下可高活性催化乙烯聚合,通过XRD、TEM、DSC表征了SBA-15负载催化剂和所得聚乙烯,结果发现:因载体的孔道效应而生成了纤维状聚乙烯.考察了反应温度、Al/Zr摩尔比对乙烯聚合活性的影响. |
| 关 键 词： | 乙烯聚合 SBA-15分子筛 二氯二茂锆 |

| Abstract: | SAB-15 supported zirconocene dichloride catalyst was prepared successfully and used for ethylene polymerization with high activity in the presence of modified methylaluminoxane(MMAO).The SAB-15 supported catalyst and polyethylene were characterized by XRD,TEM and DSC,and fibrous polyethylene was produced due to the channel effect of the support.The effects of reaction conditions such as temperature and Al/Zr molar ratio upon catalytic activity were discussed. |
| Keywords: | ethylene polymerization SBA-15 zirconocene dichloride |
