Claims27
A catalyst system comprising a catalyst compound and an activator, wherein the catalyst compound is represented by Formula (I):
- wherein:
- M is a group 8, 9, or 10 transition metal;
- L is a Lewis base;
- j is 0, 1, or 2;
- X is an anionic ligand;
- k is 0, 1, or 2;
- and
- R1, R2, R3, and R4 are independently selected from hydrogen, substituted or unsubstituted C1-C30 hydrocarbyl, —CN, —NR′2, —OR′, halogen, —NO2, —SiR′3, five-, six-, or seven-membered heterocyclyl (where each R′ is independently hydrogen, C1-C30 hydrocarbyl, and R′ is optionally substituted by halogen, or two R′ radicals optionally bond to form a five- or six-membered ring), or —SiR″3, —SiR″2(OR′″), —SiR″(OR′″)2, or —Si(OR′″)3 (where each R″ and R′ is independently hydrogen, C1-C30 hydrocarbyl, or two R″ radicals optionally bond to form a five- or six-membered ring);
- where R1, R2, R3, and R4 are optionally substituted by halogen, —NO2, —CN, —CF3, —CF2CF3, —CH2CF3, —NR′2, —OR′, —OSi(OR′)3, where each R′ is independently hydrogen, C1-C30 hydrocarbyl, and R′ is optionally substituted by halogen, or two R′ radicals optionally bond to form a five- or six-membered ring, or —SiR″3 where each R″ is independently hydrogen, C1-C30 hydrocarbyl, or two R″ radicals optionally bond to form a five- or six-membered ring;
- and
- the activator is represented by the Formula (II):
- wherein:
- M′ is selected from boron, aluminum, or gallium;
- E1, E2, and E3 are oxygen;
- Ra, Rb, and Rc are independently a C1-C22-alkyl, C2-C22-alkenyl, C6-C22-aryl, arylalkyl where alkyl has from 1 to 10 carbon atoms and aryl has from 6 to 30 carbon atoms, alkylaryl where alkyl has from 1 to 10 carbon atoms and aryl has from 6 to 30 carbon atoms, a support material, or two or more of Ra, Rb, and Rc are optionally bonded to form a five-, six- or seven-membered carbocyclic or heterocyclic ring, the heterocyclic ring being at least one atom selected from the group consisting of N, P, O and S;
- where Ra, Rb, and Rc are optionally substituted by halogen, —NO2, —CF3, —CF2CF3, —CH2CF3, —NR′2, —OR′(where each R′ is independently hydrogen, C1-C22-hydrocarbyl, and R′ is optionally substituted by halogen, or two R′ radicals optionally bond to form a five- or six-membered ring), or —SiR″3 (where each R″ is independently hydrogen, C1-C22-hydrocarbyl, or two R″ radicals optionally bond to form a five- or six-membered ring);
- w is 1;
- y is 1;
- and
- z is 1.
