Abstract
A method of manufacturing methylidene-group-containing .alpha.,.omega.-unsaturated oligomers from .alpha.,.omega.-diolefins in the presence of a catalytic amount of organoaluminum compounds, wherein the .alpha.,.omega.-diolefins are reacted in the liquid phase, at 150.degree.-350.degree. C., and the organoaluminum compounds have formula AlX.sub.3 or AlX.sub.2 H, where X represents an aliphatic, alicyclic, or aromatic hydrocarbon group with 1-30 C atoms. The higher molecular weight hydrocarbons manufactured according to this method are substantially linear oligomers which contain reactive double bonds.
