| titleOfInvention | A method for producing high molecular weight stereoregular polymers in the presence of a modified catalyst system |
| abstract | An improved method for polymerizing alpha-olefins under low pressure in the presence of a modified Ziegler-Natta catalyst comprising a mixture of an organo-aluminum compound and a compound of a transition metal of groups IV-B, V-B, VI-B, and VII-B of the Periodic Table, together with a quantity of Groups I-A and II-A organophosphide in an amount of from about .01 to about.15 moles bases upon the amount of organo-aluminum compounds present. Catalysts of the instant invention provide highly isotactic polymers. The amount of metal organophosphide added is critical to obtaining these objectives. |
