Abstract
Four ethylene-1-decene copolymers, covering a wide range of compositio ns, were analyzed in solution by means of C-13 NMR spectroscopy. A det ailed assignment of the signals to the different triad sequences was c arried out. The experimental triad distributions were compared with ca lculations assuming Bernouillian and first-order Markov statistics, fi nding a better agreement for the latter model. The triad distributions were also used for the determination of the reactivity ratios of the two comonomers.
