Descrição: The structures of 1-hexene polymer obtained with AlCl 3 without solvent at 0°C were studied by 13 C NMR spectroscopy. Only negligible amount of sequences of the 1,2-added units were observed in these polymers, signifying that the isomerization reactions take place much faster than the propagation reaction. The most remarkable findings were that longer than normal-hexyl chains and long interior methylene sequences, e.g. -(CH 2 ) 6 − , were in abundance. Structures and structural units, which imply rapid reversible successive hydride and alkide shifts, were found.
