摘要
综述了近年来硅胶载体经甲基铝氧烷 (MAO)化学处理后负载茂金属催化剂的一些研究进展 ,指出硅胶的化学活化是茂金属催化剂负载化的关键 ,单组分化学处理剂处理硅胶载体不能完全满足人们对负载型茂金属催化剂烯烃聚合的需求 ,采用含MAO的多组分化学处理剂化学活化硅胶后负载催化剂是该领域发展的趋势。
The progress of metallocene catalyst supported on silica gel treated by methylaluminoxane (MAO) is reviewed. It is pointed out that the chemical activity of silica gel is the key in the all supported process. Mono-component chemical modifier used to treat silica gel carrier can not meet the demands of olefin polymerization with supported metallocene catalysts, and maybe multi-component ones contained MAO will become the trend of this field.
