Polymerization of olefins with pre-activated catalysts |
| abstract |
A method for the polymerization of olefins using a catalyst in the form of a solid compound of a transition metal in which the transition metal is at least partially reduced to a valency state lower than the maximum valency state, with the transition metal compound being subjected prior to use to pre-activation by contact with magnesium and one or more halogenated hydrocarbons and one or more organo-metallic compounds of Groups II and III. |
