| titleOfInvention | Preparation of polypropylene in the presence of a single-site catalyst |
| abstract | Process for the preparation of a polypropylene, wherein propylene is polymerised optionally with a comonomer selected from the group consisting of ethylene, a C4-C20 a-olefin and mixtures thereof, in the presence of a catalyst system comprising solid catalyst particles, wherein the solid catalyst particles (a) comprise a transition metal compound of formula (I) LmRnMXq (I) wherein ''M'' is a transition metal of anyone of the groups 3 to 10 of the periodic table (IUPAC), each ''X'' is independently a monovalent anionic s-ligand, each ''L'' is independently an organic ligand which coordinates to the transition metal (M), each ''R'' is a bridging group linking two organic ligands (L), ''m'' is 2 or 3, preferably 2, ''n'' is 0, 1 or 2, preferably 1, ''q'' is 1, 2 or 3, preferably 2, m+q is equal to the valency of the transition metal (M), (c) comprise a cocatalyst (Co) comprising an element (E); of group 13 of the periodic table (IUPAC), preferably a cocatalyst (Co) comprising a compound of Al, wherein further the loss of activity of the solid catalyst particles during polymerization is at most 20 %. |
