论文部分内容阅读

Heterogeneous silica-supported systems, such as Phillips or Union Carbide catalysts, have been widely used in the large scale industrial production of polyolefins.1-2The ill-defined nature of these catalysts caused some heterogeneities in the produced polymers, which might be not desirable for some applications.
