| titleOfInvention | Catalysts and method for polymerization of olefins |
| abstract | A catalyst for the polymerisation of 1-olefins is disclosed comprising (1) a compound of the formula B, wherein M is Fe[II], Fe[III], Co[I], Co[II], Co[III], Mn[I], Mn[II], Mn[III], Mn[IV], Ru[II], Ru[III] or Ru[IV]; X represents an atom or group covalently or ionically bonded to the transition metal M; T is the oxidation state of the transition metal M and b is the valency of the atom or group X; R1, R2, R3, R4, R5, R6 and R7 are independently selected from hydrogen, halogen, hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl; and when any two or more of R1-R7 are hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl, said two or more can be linked to form one or more cyclic substituents; (2) an activator which is an alkylalumoxane; and (3) additionally to (2), a compound of the formula AlR3, where each R is independently C1-C12 alkyl or halo. Preferred compounds (3) include trimethylaluminium (TMA) and triisobutylaluminium (TIBA). |
