A metal composition suitable as an initiator for olefin polymerisation which is the product of reacting a particulate support material, preferably having a reactive surface which is free from water, with firstly an organometallic compound of the general formula
and secondly a transition metal organometallic compound of the general formula
wherein M is a metal of Groups IA, IIA or IIB of the Periodic Table, T is a transition metal of Group IVA of the Periodic Table, R' and R2 are hydrocarbyl or substituted hydrocarbyl groups, X, when present, is a singly charged anionic ligand or a monodentate ligand, m is 1 or 2 depending on whether the metal is in Group IA, or in Group IIA or IIB, and p is 0, 1 or 2.
一种适用于烯烃聚合引发剂的金属组合物,它是颗粒状支撑材料(最好具有不含水分的反应表面)首先与通式的有机金属化合物反应的产物,其次与通式的过渡金属有机金属化合物反应的产物 其中 M 是元素周期表中 IA、IIA 或 IIB 族的金属,T 是元素周期表中 IVA 族的过渡金属,R'和 R2 是烃基或取代的烃基,X(存在时)是单电荷阴离子配体或单齿配体,m 是 1 或 2(取决于金属是属于 IA 族还是 IIA 或 IIB 族),p 是 0、1 或 2。
