Abstract A series of MgCl 2 /NaCl/ID/TiCl 4 type supported catalysts were prepared by comilling NaCl with MgCl 2 · n EtOH adduct and reacting the mixture with TiCl 4 and internal electron donor (ID = di- n -butyl phthalate). Crystallites of NaCl were found in the doped catalysts as revealed by WAXD analysis. The NaCl doped catalysts showed lower catalytic activity and higher isospecificity in catalyzing propylene polymerization. There was a marked change of the molecular weight distribution… CONTINUE READING
