摘要：

Four ethylene-1-decene copolymers, covering a wide range of compositions, were analyzed in solution by means of C-13 NMR spectroscopy. A detailed assignment of the signals to the different triad sequences was carried out. The experimental triad distributions were compared with calculations assuming Bernouillian and first-order Markov statistics, finding a better agreement for the latter model. The triad distributions were also used for the determination of the reactivity ratios of the two comonomers.
