| titleOfInvention | Polymerization method of procatalyst particles and impact copolymer |
| abstract | The present invention provides a novel method for polymerizing a propylene impact copolymer in which the fluidity of polymer particles is maintained or improved. Particles of a procatalyst composition having a particle size D50 of 19 microns to 30 microns. Halogenating MagTi procatalyst precursor particles in the presence of a substituted phenylene aromatic diester to form procatalyst composition particles having a particle size D50 of 19 to 30 microns, first, propylene and Optionally contacting one or more first comonomers with a catalyst composition comprising particles of the procatalyst composition in a first polymerization reactor to form an active propylene-based polymer; Contacting the active propylene-based polymer with at least one second comonomer in a second polymerization reactor to form a propylene impact copolymer. [Selection figure] None |
