## Abstract The kinetics of ethylene oxidation by air over a supported silver catalyst were investigated in the temperature range 490β620 K. The reaction network was found to be triangular. Under virtually constant oxygen partial pressure (0.2 bar), the following rate relationships, (in mol g^β1^s^

## Abstract The effect of various kinds of alkylaluminium on the kinetic parameters of the initial stage of propene polymerization with MgCl~2~βsupported Ziegler catalyst was studied by the stoppedβflow polymerization method. The active sites concentration ([C^\*^]) decreased drastically with the i
The initial polymerization stage of propene with a MgClz-supported Ziegler catalyst after the pre-treatment with a Lewis base was examined as a study of the stereospecificity of the active sites precursors. A drastic depressing effect on the catalyst activity occurs, accompanied by an increase in st
