Abstract:
Particles of a procatalyst composition having a particle size D50 from 19 microns to 30 microns. A polymerization process comprising halogenating, in the presence of a substituted phenylene aromatic diester, particles of a MagTi procatalyst precursor to form particles of a procatalyst composition having a particle size D50 from 19 microns to 30 microns; first contacting a propylene and optionally one or more first comonomers with a catalyst composition comprising the particles of the procatalyst composition in a first polymerization reactor to form an active propylene-based polymer; and second contacting the active propylene-based polymer with at least one second comonomer in a second polymerization reactor to form a propylene impact copolymer.

Claim (Index 12):
A polymerization process comprising:\n halogenating, in the presence of a substituted 1,2-, 1,3- or 1,4-phenylene aromatic diester, particles of a MagTi procatalyst precursor having a particle size D50 from 26 microns to 30 microns to form particles of a procatalyst composition having a particle size D50 from 26 microns to 30 microns; first contacting, under first polymerization conditions, propylene monomer and optionally one or more first comonomers with a catalyst composition comprising the particles of the procatalyst composition in a first polymerization reactor, comprising forming an active propylene-based polymer; and second contacting, under second polymerization conditions, the active propylene-based polymer with at least one second comonomer in a second polymerization reactor to form a propylene impact copolymer.
