Abstract The gas‐phase copolymerization of ethylene with propene and 1‐butene using supported Cr‐containing catalysts of different composition and supported Ti‐Mg catalysts was studied. Comonomer reactivity ratios for 8 different catalyst systems were determined. A lower regiospecificity of the chromium oxide catalyst as compared with the titanium‐magnesium catalyst was observed, according to 13 C NMR measurements.
