Process for the preparation of propylene random copolymers |
| abstract |
A process for the preparation of a propylene random copolymer, wherein propylene is polymerised with ethylene and/or a C4-C20 alpha-olefin in the presence of a catalyst system comprising solid catalyst particles, wherein the solid catalyst particles (a) have a specific surface area of less than 20 m2 /g, (b) comprise a transition metal compound which is selected from one of the groups 4 to 10 of the periodic table or a compound of actinide or lanthanide,10 (c) comprise a metal compound which is selected from one of the groups 1 to 3 of the periodic table, and (d) comprise inclusions not having catalytically active sites. |
