| titleOfInvention | A process for the polymerization of olefins |
| abstract | Olefines are homo- or co-polymerized using a catalyst system comprising (1) a hydrocarbon-insoluble reaction product formed from a compound of a transition metal selected from metals of Groups IVa, Va, VIa and VIII (Mendeleef), and manganese and an organometallic compound of an alkali metal, alkaline earth metal, zinc, cadmium, aluminium, or rare earth metal, and (2) an organo-cadmium compound and optionally (3) a substance selected from organo-polybasic acid esters, esters of carboxylic acids with polyhydric alcohols and polysiloxanes. The polymerization may be carried out in a solvent and hydrogen may be employed to regulate the molecular weight of the product. In the examples, the catalysts employed are as component (1), the reaction product of diethylaluminium monochloride and titanium tetrachloride, as component (2) diethyl cadmium and optionally as component (3) one of the following: dimethylpolysiloxane, rape seed oil, diphenylpolysiloxane, dioctyl phthalate and glyceryl tristearate and the monomers polymerized are (a) ethylene optionally in the presence of hydrogen, (b) propylene, (c) butene-1, (d) ethylene plus propylene optionally in the presence of hydrogen and (e) styrene in the presence of hydrogen. |
