Catalytic hydrocondensation of carbon monoxide with olefins and their hydropolymerization under the influence of carbon monoxide and hydrogen

1.	The activity of cobalt-group II metal oxide catalysts in the hydropolymerization reactions of C2-C4 olefins, initiated by CO at 190°, depends on the nature of the oxide and decreases when going from BeO to BaO.
2.	In their reactivity the olefins fall into the order: C2 > C3H6 >-C4H8 > i-C4H8.
3.	The degree of reduction of the cobalt found in the catalyst depends on the nature of the employed oxide and (toes not determine its activity.
