Copolymerization of propene and 1‐olefins including 1‐octene, 1‐decene, 1‐dodecene, 1‐tetradecene, and 1‐hexadecene were studied with the catalyst system MgCl 2 /TiCl 4 ‐Al(i‐Bu) 3 . It was found that the polymerization productivity and the consumption rate of propene are improved significantly in the presence of the comonomer. The total productivity of propene/1‐olefin copolymerizations decreases as follows: 1‐octene> 1‐decene>1‐dodecene>1‐hexadecene>1‐tetradecene. The reactivity ratios were estimated from the copolymerization results. 13 C NMR was used to characterize the microstructures of propene/1‐octene copolymer. Finally, the oxygen enrichment behavior of propene/1‐octene copolymer was investigated.
