摘要:
A method for producing a polymerized hydrocarbon includes a step of a dehalogenation of a halogenated hydrocarbon with a magnesium-diene complex. Low-molecular-weight compounds, such as dimers or trimers of hydrocarbon units, oligomers of hydrocarbon units, or polymers of hydrocarbon units can be produced by this method while generating significantly less odor.
