    • A process for the polymerisation of 1-olefins is disclosed which comprises the steps of a) preparing a prepolymer-based catalyst by contacting one or more 1-olefins with a catalyst system, and b) contacting the prepolymer-based catalyst with one or more 1-olefins, wherein the catalyst system comprises (1) a compound of formula (I) 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; R?1, 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; optionally (2) an activator, and also optionally (3) a compound of the formula AlR¿3?, where each R is independently C1-C12 alkyl or halo.
    • 公开了用于聚合1-烯烃的方法,其包括以下步骤:a)通过使一种或多种1-烯烃与催化剂体系接触来制备预聚物基催化剂,和b)使预聚物基催化剂与一种或多种 其中所述催化剂体系包含(1)其中M为Fe [II],Fe [III],Co [I],Co [II],Co [III],Mn [I ],Mn [II],Mn [III],Mn [IV],Ru [II],Ru [III]或Ru [IV] X表示与过渡金属M共价或离子键合的原子或基团; T是过渡金属M的氧化态,b是原子或基团X的化合价; R1,R2,R3,R4,R5,R6和R7独立地选自氢,卤素,烃基,取代的烃基,杂烃基或取代的杂烃基; 并且当R1-R7中的任何两个或更多个是烃基,取代的烃基,杂烃基或取代的杂烃基时,所述两个或更多个可以连接形成一个或多个环状取代基; 任选地(2)活化剂,并且任选地(3)式AlR 3'的化合物,其中每个R独立地为C 1 -C 12烷基或卤素。
