| Abstract: | A kind of catalyst for gas-phase polymerization of ethylene was prepared via impregnation process. The effects of composition,micromorphology,particle size distribution,loading time of titanium and amount of titanium tetrachloride on properties of the catalysts were studied.The results show that the composition of the catalyst is similar to that of its counterpart available in the market.The catalyst has good particle morphology and narrow particle size distribution.The efficiency of the catalyst can be imp... |
