| description | A solid, particulate catalyst comprising:
(i) a complex of formula (I):
wherein
M is zirconium or hafnium;
each X is a sigma ligand;
L is a divalent bridge selected from -R' 2 C-, -R' 2 C-CR' 2 -, -R' 2 Si-, -R' 2 Si-SiR' 2 -, -R' 2 Ge-, wherein each R' is independently a hydrogen atom, C1-C20-alkyl, tri(C1-C20-alkyl)silyl, C6-C20-aryl, C7-C20-arylalkyl or C7-C20-alkylaryl;
each R 1 independently is a linear or branched C1-C20 hydrocarbyl radical optionally containing one or more heteroatoms from groups 14-16;
T 1 and T 4 , which can be the same or different, are an OR 2 , a SR 2 , CH(R 18 ) 2 , CH 2 R 18 , aryl or heteroaryl group;
each R 2 , which can be the same or different, is a C1-C20 hydrocarbyl radical;
each R 18 , which can be the same or different, is a C1-C20 hydrocarbyl radical or two R 18 groups together with the carbon atom to which they are attached may form a cyclic C4-C20 hydrocarbyl group;
T 2 and T 3 , which may be the same or different, are a C(R 18 ) 3 group;
W 1 and W 2 , which may be the same or different, are a 5 or 6 membered aryl or heteroaryl ring wherein each atom of said ring is optionally substituted with an R 5 group;
each R 5 , which can be the same or different, is a C1-C20 hydrocarbyl radical optionally containing one or more heteroatoms belonging to groups 14-16; and optionally two adjacent R 5 groups taken together can form a further mono or multicyclic ring condensed to W 1 or W 2 , optionally substituted by one or two groups R 5 ;
and (ii) a cocatalyst. |
