The degree of alternation in the resulting copolymers is higher than 92.1% for all the copolymers and close to 100% for ethylene-1-decene copolymer. Copolymerization behaviours focusing on the misinsertions during the polymerizations are investigated in detail from dyad and triad distributions estimated by 13C NMR analysis of copolymers. A reactivity ratio, rBE, was obtained for ethylene-1-hexene copolymers using a simplified two sites alternating mechanism and found to be 8.7, which is the same order of that reported in ethylene-propene copolymerizations with Me2C(3-RCp)(Flu)ZrCl2-MAO as the catalyst system.
