Preparation of precipitated ZN PP catalysts with internal pore structure using nanoparticles

The invention refers to a process for preparing a Group 2 metal/transition metal olefin polymerization catalyst component in particulate form for polymerizing olefins, especially ethylene or propylene or comonomers thereof.

Catalyst component

The invention refers to a process for preparing a Group 2 metal/transition metal olefin polymerisation catalyst component in particulate form free of conventional phthalate electron donors and the use thereof in a process for polymerising olefins.

The invention refers to a process for preparing a Group 2 metal/transition metal olefin polymerization catalyst component in particulate form having improved polymerization properties due to the use of Hduring catalyst component preparation and the use of such catalyst components in a process for polymerizing olefins.

Catalyst preparation using H2

[object Object]

The invention is directed to a process for the manufacture of heterophasic propylene copolymer compositions comprising the steps of forming a propylene polymer matrix in at least one slurry reactor and optionally in at least one gas phase reactor and subsequently forming in at least one gas phase reactor an elastomeric copolymer by copolymerizing propylene with ethylene and/or with another alpha-olefin in the presence of said matrix, wherein the polymerization is carried out in the presence of a catalyst system comprising a catalyst in form of solid particles, said particles (a) have a surface area of less than 20 m/g, (b) comprise a transition metal compound of groups 4 to 10 of the periodic table or a compound of actinide or lanthanide, (c) comprise a metal compound of groups 1 to 3 of the periodic table, and (d) comprise inclusions not comprising catalytically active sites.
