Abstract:
Co-polymerization of ethylene and 1-hexene using rac-Et[Ind]2ZrCl2/MAO catalyst embedded in polystyrene in liquid slurry process was examined. The embedded catalyst was prepared by polymerizing a small amount of styrene. The specific activities and bulk densities of the copolymers produced by the embedded catalyst were higher than those of the homogeneous catalyst. The produced co-polymer with embedded catalyst had more random distribution of 1-hexene at the similar co-monomer content than that with homogeneous catalyst.Keywords: CO-POLYMERIZATION; RAC-ET[IND]2ZRCL2/MAO; METALLOCENE CATALYST
