Abstract: JC catalyst was prepared by using magnesium ethoxide as the carrier and adding the third component. This paper
introduced the preparation and basic performance of the catalyst, with the simple preparation process, good particle shape, high
activity and narrow particle size distribution of JC catalyst. JC catalyst was used in the interval pilot polymerization by slurry process
to produce UHMWPE. It showed the stable operation of the plant, stable control of the molecular weight of each batch of products,
the concentrated distribution of produced UHMWPE particle size, higher than 0.42 g/cm3 of the bulk density, less content of the fine
powder, which had good physical and mechanical properties, and the good processing performance of pilot products. The inner and
outer surfaces of the processed pipe products were smooth, and the physical and mechanical properties of the pipe products were better
than those of UHMWPE, which indicated that JC catalyst can be used to produce UHMWPE.
