The product of 1‐decene oligomerization with AlCl 3 as catalyst was fractionated by vacuum distillation, with the highest fraction consisting predominantly of the hexamer. The structure of the fractions was characterized by 1 H and 13 C NMR and Raman spectroscopy. The oligomers contain predominantly long branches (7 carbons and longer) and always one double bond per molecule, with strong predominance of tri‐ and tetra‐substituted types. The minority structures are analyzed, and the polymerization and isomerization mechanisms are discussed.
